NCAA Tournament TV Schedule 2015: Updated Bracket, Must-See Matchups on Friday

Don't beat yourself up over a bruised bracket after Thursday's unpredictable results at the NCAA tournament. 

The opening day of the round of 64 saw multiple 13 seeds win, several one-point games and even a handful of no-contest matchups. It truly was a unique day, even by March Madness' standards. It was so nutty that SI.com's Seth Davis took to Twitter to express his excitement:

There's even more on the schedule for Friday, as 16 more matchups will be decided throughout the day. Nobody would blame you for watching all 16, but be sure to check out the following three. They're must-sees. 

No. 7 Iowa vs. No. 10 Davidson

Iowa is going to have its hands full against Davidson.

The Wildcats finished their first season in the Atlantic 10 Conference with a 24-7 record after picked to finish toward the bottom of the field in the preseason. Tyler Kalinoski was the A-10 Player of the Year with averages of 17.0 points, 5.6 rebounds and 4.1 assists per game.

But the senior guard isn't the only player the Hawkeyes need to worry about. Jack Gibbs, Brian Sullivan and Jordan Barham each averaged at least 11.9 points per contest, and this Davidson squad ranked sixth in the country by dropping 79.9 points per night.

While the talent is obviously important, it all comes down to the coaching. Bob McKillop, now in his 26th season as head coach at Davidson, doesn't run many set plays. He lets his stars make the decisions.

Kalinoski told The Associated Press (via FoxSports.com):

"

It's just a lot of fun out there. We're not going to slow the game up and run a bunch of plays. Coach isn't going to yell at us to run a certain type of play every time on the court. He trusts us to make good decisions. And you just feel free out there playing a game you love. So it's a lot of fun.

"

Containing Kalinoski will inevitably free Gibbs, a 44.1 percent shooter from distance. Iowa must get creative defensively, otherwise the Wildcats will earn the upset.

Something that might hurt Davidson is its lack of size compared to Iowa, as Chad Leistikow of the Des Moines Register tweets:

Should they get past Iowa's size, the Wildcats are a candidate to sneak into the Sweet 16.

No. 13 Valparaiso vs. No. 4 Maryland

In a matchup that could go either way, look for Maryland to continue to rely on the successful trio of Melo Trimble, Dez Wells and Jake Layman.

They averaged 44.5 points per game during the regular season, well more than half of the team's 69.5 season average. Trimble was an All-Big Ten first-team selection by the media, while Wells was an All-Big Ten first-team selection by the coaches.

Valpo coach Bryce Drew is aware of the Terrapins' strong guard play by Trimble and Wells, and he told Michael Osipoff of the Chicago Tribune about how difficult it will be for his team to defend them.

"They're both tough matchups," he said. "They're bigger than a lot of the guards we're used to defending, and stronger. It'll definitely be a big challenge for our perimeter defenders."

While it might be uncommon for the Crusaders' defenders to play against bigger guards (Trimble is 6'2" and Wells is 6'5"), the overall defensive showing should still be above average. The Crusaders ranked 17th in the nation in that area, allowing just 59.3 points per contest. They even held five teams under 50 points.

It'll be Valpo's swarming defense that wins the game for Drew, not the offense. While not offensively inept, the team really only relies on Alec Peters to make shots when it needs points. He's a very talented player, shooting 49 percent from the field and over 46 percent from deep, but he can't do it by himself.

That's why the defense is so important. It inherently limits the type of impact the other players need to have on offense.

Given how Trimble and Wells will challenge this stifling unit, this game is a must-see.

No. 11 Dayton vs. No. 6 Providence

Dayton won a First Four game against Boise State to advance to this contest against Providence, but the Flyers never should have been put in that position. Yahoo Sports' Jeff Eisenberg wrote about how underappreciated they are:

"

The Flyers finished a game out of first place in the Atlantic 10 despite playing the entire conference season with six scholarship players and none taller than 6-foot-6 as a result of the December dismissal of their two top big men. They won 25 games, defeated seven RPI top 100 opponents and only suffered one mediocre loss all season, yet the selection committee relegated them to the First Four behind a handful of teams with lesser resumes.

"

Perhaps the committee saw the lack of height on the roster and that raised some red flags. But, hey, the Flyers have been very successful without a menacing rim protector on the team. That shouldn't stop now.

Dyshawn Pierre, a 6'6" forward, led the team with 8.1 rebounds per game. He also dropped 12.6 points per game as an inside-outside threat, making him the key player whom Providence must focus on containing. It won't be easy because of his versatility, but the Friars must do something to force him outside and take contested jumpers, rather than easy shots in the paint.

Kris Dunn, a 6'3" guard, may be tasked with the assignment—at least on the perimeter. He averaged 2.8 steals per game, so look for him to try and cause havoc outside before other defenders swarm to help him once Pierre makes his way closer to the basket.

This is going to be a back-and-forth affair. Pierre and Jordan Sibert will compete with Dunn and LaDontae Henton to see which duo can lead its team to the round of 32.

Dayton is undervalued, though, so don't sleep on the Flyers.
