Parker's decision helps Mike Krzyzewski and the Blue Devils leap far up in the Top 25 for 2013 college basketball recruiting classes.
After this monumental commitment, let's examine how Parker's highly anticipated choice shakes up our monthly rankings.
Star Power: Macon was not originally part of the Class of 2013, but he and Williams are both elite big men. These two twin towers will give the Mountaineers a huge boost inside on both ends of the court thanks to their skilled post moves and rebounding prowess.
Irons in the Fire: PF Junior Etou and SG Shacore Edwards aren't star recruits, but they could be four-year players who could have a big impact down the road.
Bottom Line: Bob Huggins desperately needs to find a way to improve a backcourt that ranks No. 226 in the nation in assists per game, and bringing in four big men and zero guards doesn't help in that aspect.
Commits: SG Matt Thomas (No. 34, ESPN), PG Monte Morris (No. 82)
Star Power: Thomas and Morris make up an electric backcourt that will help bring Iowa State back to the top. Morris will be able to create for Thomas and set up his elite shooting stroke.
Irons in the Fire: Four more recruits are considering the Cyclones, with SG Martez Walker being the best among them.
Bottom Line: Losing five guards and a forward hurts Iowa State, but Thomas, Morris and JUCO transfers PF Richard Amardi and SF Dustin Hogue will help the Cyclones stay competitive.
Commits: SG Kendrick Nunn (No. 59, ESPN), SG Malcolm Hill (No. 92), C Maverick Morgan (Unranked), PF Austin Colbert (Unranked), PG Jaylon Tate (Unranked)
Star Power: Hill's length and athleticism allow him to play wing, and having him on the court at the same time as lights-out shooter Nunn is practically unfair.
Irons in the Fire: John Groce already has five commits, but with seven more still considering Illinois, we could see this class continue to grow.
Bottom Line: Losing star guard Brandon Paul will hurt, but Groce already has replacements for his best player. Look for Illinois to stay strong under its new coach.
Commits: PG Stevie Clark (No. 62, ESPN), SG Detrick Mostella (No. 83), SF Leyton Hammonds (Unranked), SF Jeff Carroll (Unranked)
Star Power: Clark and Mostella are both score-first guards who can light up the scoreboard, and if Travis Ford can get them to work together like Marcus Smart and Le'Bryan Nash are, they could be deadly.
Irons in the Fire: Two more recruits are still considering Oklahoma State, with PF Brian Bridgewater being the most important of the two, as he would help the Cowboys inside.
Bottom Line: With the futures of Smart and Nash unknown, it's a good thing that Ford is bringing in a few talented guys to keep OK State elite.
Commits: PF Johnathan Williams III (No. 37, ESPN), PG Wes Clark (No. 74), PF Torren Jones (Unranked)
Star Power: JW3 highlights this class, with his athleticism always helping him find ways to impact the game on both ends of the floor.
Irons in the Fire: Five guys are still looking at Missouri, and another power forward in Demetrius Henry is the best available recruit.
Bottom Line: Missouri's future relies heavily in the hands of junior point guard Phil Pressey, but if he returns to join forces with Williams III, we could see Missouri be a difficult opponent to stop next season.
Commits: PG Zach LaVine (No. 51, ESPN), SG Allerik Freeman (No. 54), SF Noah Allen (Unranked)
Star Power: Like so many other schools on this list, UCLA has found its backcourt of the future in the combination of LaVine and Freeman.
Irons in the Fire: Ben Howland has one great recruit left considering him in PG Rysheed Jordan. It's going to be difficult to bring the Philadelphia native to Westwood, but he would be a huge pickup for the Bruins.
Bottom Line: UCLA already has a solid core of big men for next season, and adding these guards will help the team immensely.
Commits: SG Xavier Rathan-Mayes (No. 26, ESPN), PF Jarquez Smith (No. 80)
Star Power: Rathan-Mayes and Smith both have supreme potential and could be dangerous weapons at Florida State.
Irons in the Fire: ESPN's No. 1 overall recruit, Andrew Wiggins, is FSU's top target, but having him come to a historically bad loss to Florida at home probably didn't help.
Bottom Line: Florida State still needs to find a distributor, and neither Rathan-Mayes nor Smith will fill that void.
Commits: SF Ishmail Wainright (No. 28, ESPN), C Dominic Woodson (No. 81 ESPN), PF Johnathan Motley
Star Power: Wainright is going to thrive in transition at Baylor, and he should become one of the top players in the country in a few years.
Irons in the Fire: Three more recruits are considering Baylor, but even landing any of them wouldn't help this class very much.
Bottom Line: The Bears are losing Pierre Jackson and don't have a replacement, but if the team can find a good point guard, it could be a national contender.
Commits: PG Nick Emery (No. 61, ESPN), C Eric Mika (No. 76), PF Luke Worthington (Unranked), PF Jakob Hartsock (Unranked), PF Braiden Shaw (Unranked)
Star Power: Emery and Mika will make up a great inside-outside combination, the likes of which BYU has not had in years.
Irons in the Fire: Some people were still holding out hope that Jabari Parker would pick the Cougars, but now the only recruit still considering BYU is SG Connor Toolson.
Bottom Line: BYU is trying to get back to the success it enjoyed with Jimmer Fredette, and while landing Parker would have helped, these five recruits will help the Cougars come close.
Commits: SF Rondae Jefferson (No. 17, ESPN), SG Elliott Pitts (No. 91)
Star Power: Jefferson is one of the best athletes in the Class of 2013, and bringing his up-tempo style to Tuscon is going to help Sean Miller's Wildcats.
Irons in the Fire: Speaking of athletes, arguably the best athlete in the class, Aaron Gordon, is still thinking about Arizona, and combining him with Jefferson would be practically unfair.
Bottom Line: Arizona is going to be a young team after putting together two elite classes, and the school will have a lot of potential down the road.
Commits: PF Bobby Portis (No. 11, ESPN), C Moses Kingsley (No. 49)
Star Power: Portis and Kingsley are going to make up an incredible frontcourt next season, as Portis' athletic style complements Kingsley's inside game.
Irons in the Fire: Arkansas is done in the Class of 2013, as no more recruits are considering the Razorbacks.
Bottom Line: Arkansas is going to need these two guys to be stars if the team is to be competitive in the SEC.
Commits: SF Deonte Burton (No. 42, ESPN), PG Duane Wilson (No. 57), SG JaJuan Johnson (No. 64), PG John Dawson (Unranked)
Star Power: Marquette is bringing in a brand-new perimeter, with Wilson leading Johnson and Burton.
Irons in the Fire: If these five guys weren't enough for you, Marquette is still chasing four more recruits, including a pair of power forwards who could bolster the frontcourt.
Bottom Line: Marquette lacks much star power this season, but in a year or two, you can expect a few of these guys to blossom into excellent players.
Commits: PG Demetrius Jackson (No. 21, ESPN), SG Steve Vasturia (No. 87), SF V.J. Beachem (No. 95), PF Austin Torres (Unranked)
Star Power: Jackson is the star of this class, but Vasturia and Beachem will help him keep Notre Dame as a national contender in whatever conference it ends up playing in.
Irons in the Fire: Mike Brey is done in the Class of 2013, but he made his mark with these guys.
Bottom Line: Notre Dame addressed its biggest need in a big way. The team desperately needed a point guard, and now Jackson can lead the team for a few years.
Commits: SF Zak Irvin (No. 24, ESPN), PG Derrick Walton (No. 35), PF Mark Donnal (No. 99)
Star Power: Walton will have the tough task of replacing Trey Burke, but with Irvin and Donnal around him, he should have some good options to help him run the offense.
Irons in the Fire: Michigan is another school that is done in the Class of 2013, but the Wolverines made a big splash during their time on the recruiting trail.
Bottom Line: Michigan did a good job replacing its backcourt that will likely be gone next season, so the Wolverines should remain competitive in the Big Ten next season once again.
Star Power: Rozier is going to have to replace the best floor general in the country (Peyton Siva), but Gill and Agau will be right beside him to help him out.
Irons in the Fire: SG Isaiah Lewis is the only player still thinking about Louisville, but even if he does commit, he will be stuck behind Gill.
Bottom Line: Louisville should be able to stay among the nation's elite, as these three guys will be instrumental for the Cardinals next season.
Commits: PF Jarrell Martin (No. 15, ESPN), PF Jordan Mickey (No. 47), PG Tim Quarterman
Star Power: LSU just needs some form of talent after going 7-9 in SEC play last season, and this is going to be the best class the Tigers have had in at least a decade.
Irons in the Fire: SG Keith Frazier is the only Top 100 recruit still on the market for LSU, and adding him would make this the ideal class for the Tigers.
Bottom Line: This is a very skilled class that will help LSU rise in the SEC standings.
Commits: PG Anthony Barber (No. 14, ESPN), C BeeJay Anya (No. 32), PF Kyle Washington (No. 69)
Star Power: It seems like the only recruits Mark Gottfried brings in are stars, and these three are no different. Each player in this class has the potential to do big things for the Wolfpack.
Irons in the Fire: No. 3 recruit Julius Randle is still thinking about North Carolina State, and if he picks the Wolfpack over Kentucky, this class would vault up the rankings very quickly.
Bottom Line: These guys are all great players who could all have a major impact in Raleigh. They will join a young, talented squad under Gottfried that will be looking for a national title.
Commits: PF Tyler Roberson (No. 27, ESPN), PG Tyler Ennis (No. 44), SG Ron Patterson (Unranked), SF B.J. Johnson (Unranked), C Chinonso Obokoh (Unranked)
Star Power: The two Tylers headline this class, but don't sleep on the other three guys, all of whom could emerge as great players in three years or so.
Irons in the Fire: Syracuse is still technically going after No. 1 recruit Andrew Wiggins and No. 12 recruit Dakari Johnson, but it is unlikely that it lands anyone else.
Bottom Line: Syracuse has always been a deep team, and bringing in five more recruits will keep it that way. Even losing point guard Michael Carter-Williams two years early wouldn't kill the team right now because of Ennis.
Commits: SF Jabari Parker (No. 2, ESPN), SG Matt Jones (No. 36), SF Semi Ojeleye (No. 41)
Star Power: Duke lucked out in the Jabari Parker sweepstakes, bringing in arguably the brightest star in the country.
Irons in the Fire: After landing Parker, Duke is done in the Class of 2013, as no other recruits are considering the Blue Devils.
Bottom Line: The losses of Mason Plumlee, Ryan Kelly and Seth Curry will be considerably lessened by adding Parker, Jones and Ojeleye.
Commits: PG Kasey Hill (No. 9, ESPN), PF Chris Walker (No. 10)
Star Power: This class only has two guys, but both of them are virtually guaranteed to be stars next season. They will help Florida compete in a tough SEC.
Irons in the Fire: Jabari Parker snubbed Florida, but No. 3 Julius Randle and No. 12 Dakari Johnson could both add depth to this already stellar class.
Bottom Line: Look for Hill and Walker to provide a sensational inside-outside combo that will help Florida remain among the nation's elite next year.
Commits: PF Isaiah Hicks (No. 18, ESPN), C Kennedy Meeks (No. 20), PG Nate Britt (No. 52)
Star Power: Roy Williams started with a slick inside-outside combination of Hicks and Britt, and adding another big man like Meeks makes this class even more formidable.
Irons in the Fire: North Carolina is still pursuing No. 1 overall recruit Andrew Wiggins, but the school appears to be on the outside track.
Bottom Line: UNC is built around skilled point guards and monstrous big men, and this class epitomizes that. Look for these guys to work well in Williams' system.
Commits: PF Austin Nichols (No. 13, ESPN), SF Kuran Iverson (No. 29), SF Nick King (No. 31), PG Rashawn Powell (No. 93), SG Markel Crawford (Unranked)
Star Power: Memphis is getting a makeover with this recruiting class, as combining these five guys with freshman center Shaq Goodwin could make up a deadly team.
Irons in the Fire: Seven guys are still considering the Tigers, with SG Keith Frazier leading the way. His addition to this impressive class could potentially put the Tigers in the running for the No. 1 class in the country.
Bottom Line: This is an extremely talented class that should be the shot in the arm Memphis is looking for. These guys should be around for a few years and will be able to bring Memphis to the top as it joins the Big East.
Commits: PF Noah Vonleh (No. 8, ESPN), SF Troy Williams (No. 33), SG Stanford Robinson (No. 58), PF Luke Fischer (Unranked), SF Devin Davis (Unranked), SF Collin Hartman (Unranked)
Star Power: The reason Indiana is so high on this list is because of Vonleh, who easily has the most potential of any player in the Class of 2013. If Tom Crean can turn him into a basketball player, the nation needs to watch out.
Irons in the Fire: Crean has already locked up his six guys, and he is done on the recruiting trail.
Bottom Line: This is another deep class that Indiana brings in, and if a few of these guys turn out to be stars, Indiana will remain among the nation's best for years to come.
Commits: SF Wayne Selden (No. 16, ESPN), PG Conner Frankamp (No. 39), SG Brannen Greene (No. 43), C Joel Embiid (Unranked)
Star Power: Kansas sill have a brand-new perimeter with Selden, Frankamp and Greene, and these guys will combine to give the team a fast and furious attack.
Irons in the Fire: Andrew Wiggins and Julius Randle are both still on the radar for the Jayhawks, but I'd be very surprised if either actually picked Kansas.
Bottom Line: Bill Self is bringing in four new toys, and you can bet that he is going to get the most out of these guys.
Commits: PG Andrew Harrison (No. 3, ESPN), SG Aaron Harrison (No. 5), SG James Young (No. 6), PF Marcus Lee (No. 30), PF Derek Willis (Unranked)
Star Power: The Harrison twins will immediately make up one of the best backcourts in the country, and Young on the wing will add to the Wildcats' fierce outside attack.
Irons in the Fire: Kentucky still has four elite recruits considering it, and appears to be among the front-runners for each. If the team snags Andrew Wiggins, Julius Randle, Aaron Gordon or Dakari Johnson, then this will be, hands down, the best recruiting class in history.
Bottom Line: This is the best class I've ever seen John Calipari assemble. He's the best recruiter in college basketball history, but this class simply tops all the rest.
