Are you having fun yet?

The Round of 64 is in the books, and we are down to 32 teams remaining in the NCAA Tournament. With a historic first day during which there were five games decided by a single-point (the record for one-point games in an entire NCAA tournament is six), including two upsets of 3 seeds, the games have been super exciting thus far.

To keep your adrenaline pumping for Saturday's games, I've taken key numberFire analytics (specifically suffered a sprained knee on Thursday.

Contending with the numberFire Live tool showed how dominant Jakob Poeltl was against the shorter Lumberjacks (18 points, 8 rebounds and 5 blocks) for the Utes.

The key matchup to watch is Wright, who had 8.2 Win Shares this season (second-best in the country) against Georgetown's leading scorer D'Vauntes Smith-Rivera (16.5 points per game, 86.1% free throw percentage) who had 25 points and 8 rebounds in the opener. A secondary matchup to watch is Poeltl against Georgetown senior center Joshua Smith (6'10", 350 pounds), who averages 10.8 points in only 20.6 minutes per game.

The Hoyas will hope to stroke the three like they did on Thursday night going 11-23 (47.8%) while Utah seeks a similar performance in defending the three 5-26 (19.2%).

North Carolina (4 seed, 9th) vs. Arkansas (5 seed, 25th)

Another 4 versus 5 matchup we really like is North Carolina, who narrowly escaped a tough Harvard team, against Arkansas, who escaped Wofford in the 5 versus 12 game, surprisingly played at Wofford's slow pace. This game figures to be ranked ninth overall in the first round.

On offense, Ohio State is as consistent as you can get, but on defense, they will have a really tough task in defending Brandon Ashley (who missed 2014 NCAA Tournament with a broken foot) and Arizona's huge frontcourt as the Buckeyes are fairly small. Oft-maligned Buckeyes center Amir Williams doubled his 6.4 points per game average in the first round with 13 points. An encore will be essential.

For Arizona, the Wildcats hope to have all five starters in double-figures again like their blowout win over Texas Southern on Thursday. Arizona shot 60.4% from the field and 24-27 (88.9%) from the free throw line.

In spite of being a highly rated offensive team with above average pace, look for star point guard T.J. McConnell to slow the tempo down perhaps against the Buckeyes to take advantage of the Wildcats' size up front.
