1. Wichita State became the second Missouri Valley Conference team to defeat a No. 1 seed, beating Gonzaga. The other was Northern Iowa, which beat Kansas in 2010. Kansas was also the last team ranked No. 1 in the country in the Associated Press poll entering the NCAA tournament to lose in the round of 32.
Gonzaga did not beat a team this season which won a game in the round of 64.
2. Oregon made it six consecutive seasons that a team seeded No. 12 or lower advanced to the Sweet 16. This is longest such streak since the field expanded to 64 teams in 1985. The next-longest streak is five years, from 1990-94.
But none of the teams that did so from 2008 to 2012 won their Sweet 16 game. The only team seeded 12th or worse to win a Sweet 16 game was Missouri in 2002.
The Ducks shot 72.7 percent from 3-point range Saturday, the best by any team in an NCAA tournament game since Boston College Eagles shot 75 percent in 2004.
3. Michigan and Michigan State advanced to the Sweet 16 with victories, marking the first time that both have reached that round in the same year. Michigan beat Virginia Commonwealth by 25, the worst loss for a team that won its previous NCAA tournament game by at least 40 points, and the worst loss in Shaka Smart’s head-coaching career.
The Big Ten is 8-1 in the NCAA tournament, winning by an average of more than 15 points per game. Big Ten teams have won five games by at least 20 points, the most 20-point wins the conference has ever had in the tournament.
4. Louisville is the 15th team since 1985 to win its first two NCAA tournament games by at least 25 points. But only one of the previous 14 teams to do so (2005 North Carolina) went on to win the national championship.
The Cardinals scored 24 points off 20 Colorado State turnovers Saturday. The Cardinals are now 25-0 in the past two seasons when they score at least 24 points off turnovers in a game, including 17-0 this season. Louisville used its full-court press to turn Colorado State over, forcing 13 turnovers on possessions that began with the press.
5. Quirk of the day: Mark Lyons was 8-for-8 in the paint in Arizona’s win Saturday. With the Wildcats winning, Lyons wil become the first player to play in the Sweet 16 in consecutive seasons for two different teams.
Lyons played in the Sweet 16 for Xavier Musketeers last year, than became a graduate transfer at Arizona. In seven NCAA tournament games with Xavier, Lyons never shot better than 50 percent in the paint.
