The NCAA Tournament may start with 68 teams, but it only takes two rounds to whittle that total down to 16.

Heading into the Sweet 16 of the 2014 NCAA Tournament, we will see three double-digit seeded teams in action and at least one will advance. Upsets have been plentiful thus far and we may be set up to see even more.

In the round of 34, SF Austin, Harvard, Mercer and North Dakota State could not follow up their epic first round upsets with a second win in a row. UCLA beat SF Austin, title game favorites Michigan State ended Harvard's hopes, Tennessee defeated Mercer and San Diego State took down North Dakota State.

Dayton (11) vs. Stanford (10): March 27, 7:15 p.m.

Still, Dayton kept its improbable run alive by beating Syracuse one game after upsetting Ohio State in the first round. Stanford also continued its run by beating a heavy Elite Eight favorite in Kansas. Dayton and Stanford's matchup Thursday guarantees a double-digit seeded team will be in the Elite Eight.

Baylor (6) vs. Wisconsin (2): March 27, 7:47 p.m.

Baylor held Creighton's Doug McDermott, a Wooden Award favorite to 15 points, nearly half of his average points per game this season. They will need to bring that defense against a Wisconsin team averaging 80 points in two tournament games.

Florida (1) vs. UCLA (4): March 27, 9:45 p.m.

Florida's defense will be tested by UCLA's high-powered offense, but the Gators will also benefit from going up against what has been a notoriously soft Bruins defense.

Arizona (1) vs. San Diego State (4): March 27, 10:17 p.m.

Arizona seems to have found their rhythm since slipping up briefly after losing Brandon Ashley for the season. Their offense clicked against Gonzaga and their defense has surrendered an average of 60 points through two games in the tournament.

Tennessee (11) vs. Michigan (2): March 28, 7:15 p.m.

Tennessee may have caught a break when Mercer beat Duke, because the Vols trounced the Bears by 20 points. We will never know what would have happened if Tennessee had to play Duke, but any team that makes a deep tournament run needs to catch at least one break.

Iowa State (3) vs. UConn (7): March 28, 7:27 p.m.

Iowa State's offense has looked phenomenal, but their defense has surrendered point totals of 77 and 83 in the first two rounds, respectively. UConn, on the other hand, is coming off a convincing 77-65 victory over Villanova, the second seed in the East.

Kentucky (8) vs. Louisville (4): March 28, 9:45 p.m.

John Calipari and Kentucky fought their way into the Sweet 16 by handing Wichita State its first loss all season. They are now scheduled to face Louisville, a team picked by many experts and pundits to make the title game. Despite the rocky end to their season, Kentucky has pulled out a pair of tough wins in the first two rounds of the tournament.

Virginia (1) vs. Michigan State (4): March 28, 9:57 p.m.

Anyone with a somewhat respectable bracket will be watching Friday's late games with great interest. Most of the nation's experts and pundits have Michigan State and Louisville playing for the title. Michigan State will have to first go through a Virginia team that allowed 55.5 points per game this year, the smallest average in the nation.
