National Signing Day is one of the most exciting days on the college football calendar, and this year is going to be no different.
After months and sometimes years of going through the recruiting process, this is the day where the pen finally hits paper and National Letters of Intent are signed. It's also a day filled with drama, shakeups and even flips.
Many recruits will be making their final decisions known on National Signing Day, and 2013 should feature some big-time announcements.
Recruiting classes will be impacted and the rankings will be drastically changed.
Here are five recruits that will make a huge impact on the recruiting rankings on National Signing Day.
Tyrone Crowder is arguably one of the more underrated recruits in the 2013 class.
He's 6'1'', 330 pounds and he's the No. 3 overall guard prospect in the country according to the 247Sports composite rankings. He's gone somewhat under the radar, but there's no doubting that he's going to be a big-time pickup.
According to 247Sports, Clemson is listed as his favorite right now, but both Georgia and North Carolina are listed as "warm interests." If Clemson can get his commitment, he would provide a huge boost to a Tigers class that once featured No. 1 overall recruit Robert Nkemdiche.
If Georgia can get him to sway his interest to its program though, his addition could make Mark Richt's 2013 class one of the best in the nation.
Dave Hooker of ESPN RecruitingNation reports that Crowder will likely wait until National Signing Day to announce a decision.
That will be one of the more important announcements on a day filled with important decisions.
Matthew Thomas is another highly-talented recruit that deserves to be discussed more. He's a 5-star outside linebacker and is ranked No. 2 at the position according to the 247Sports Composite rankings.
Thomas has Florida State at the top of his interest list (247Sports), but he also has interest in Alabama, Georgia and Miami.
He is from Miami, Florida, so the Hurricanes have a huge "home-town advantage," but he does have official visits scheduled to Alabama, USC, Florida State and Georgia.
His last visit is scheduled for February 1, and it will be to Georgia.
Thomas' commitment doesn't appear to be a lock in any which way, so his decision will be a very intriguing one.
Reuben Foster is a former Auburn commitment, but now he's one of the biggest uncommited recruits in the 2013 class.
Since decommiting from Auburn, Georgia has been the main player for his commitment, and he has an official visit lined up for the Bulldogs as well as one to Washington (Kipp Adams/ESPN). Other programs like LSU, Miami and South Carolina are also in the mix for visits, and don't count out Auburn just yet.
Foster is the No. 1 ranked inside linebacker in the 2013 class according to the 247Sports composite rankings, so he's going to be a huge commitment. If a program like Georgia or LSU can land him, his commitment alone would make their class elite.
Considering all the visits he wants to take, this is a decision that should come down to the wire.
Montravius Adams is arguably the best defensive lineman in the 2013 class, and he's got an interest list that would back that statement up.
247Sports has an unofficial top five of Georgia, Florida, Alabama, Auburn and Clemson listed for the elite defensive tackle, and he has official visits set up with Florida, Clemson, Alabama and Georgia.
This is another decision that I expect will come down to National Signing Day. With all the visits he wants to take, it just makes the most sense.
When he does decide, his commitment will really shake up the recruiting rankings.
There will be no bigger moment during National Signing Day than the moment when Robert Nkemdiche announces his decision.
The No. 1 overall recruit has made headlines all year—especially when he decommited from Clemson—but this will be his biggest decision to date.
This commitment will be official, and it's a commitment that may drastically shake up the recruiting rankings.
Ole Miss is thought to be the favorite for his commitment because of his family ties to the program, but 247Sports has Alabama and LSU listed as "warm interest" as well.
Landing his commitment would be a huge boost for Ole Miss, but if he were to join LSU it could propel the Tigers to the No. 1 overall ranking. For Alabama, Nkemdiche's commitment would essentially secure its spot on top of the rankings (Alabama is currently ranked No. 1 overall by Rivals.com).
Either way you look at it, Nkemdiche's final decision will be the biggest one of the 2013 recruiting cycle.
