After two days of mild results, madness returned to the NCAA Tournament on Saturday.
No. 1 overall Villanova fell to No. 8 Wisconsin in heart-breaking fashion. No. 8 Northwestern pushed No. 1 Gonzaga to the brink, and No. 11 Xavier destroyed No. 3 Florida State.
Sunday's slate of games offers a litany of upset potential, and the mighty ACC Conference could be entirely eliminated from the tournament — only Duke, North Carolina and Louisville remain in the field.
Here are Sunday's most intriguing games:
No. 7 Michigan vs. No. 2 Louisville (12:10 p.m. ET on CBS)
The Wolverines lit up the scoreboard while torching Oklahoma State from beyond the arc Friday. Michigan, after winning the Big Ten Tournament, knows how to meander its way through a group of talented teams. Dealing with Louisville's length in passing lanes will be tough for Michigan, but it's hard to bet against them right now while Derrick Walton Jr. is leading the way, offensively.
Rick Pitino has groomed thisunderrated team into title contenders. Led by guards Quentin Snider and Donovan Mitchell, the Cardinals are stingy on defense and deceptively opportunistic on offense. Deep and rangy, Louisville can put up points in bunches.
No. 9 Michigan State vs. No. 1 Kansas (5:15 p.m. ET on CBS)
After trailing by 12 points early Friday against Miami, Michigan State and its quartet of super freshman roared back to beat the Hurricanes by 20 points. This matchup pitsMiles Bridges and Cassius Winston against Kansas'Josh Jackson, who is a friend of both MSU players.The trio makes up three of the best freshmen in the nation, and it will be thrilling to see Bridges and Jackson match up against each other.
The Spartans were considered possible tournament outsiders in mid-February, but a win against Wisconsin helped them get in. Now, Tom Izzo is ready to continue his reputation as a giant-killer in March.
No. 6 Cincinnati vs. No. 3 UCLA (9:40 p.m. ET on TBS)
The Bearcats are known for their slow, methodical tempo that frustrates its opponents into mistakes. UCLA, on the other hand, wants to push the ball up the court and score 90 points or more every game. This could turn into abasketball version of the tortoise and the hare. Either pure talent or patience will reign supreme.
Lonzo Ball scared Bruins fans by temporarily going down against Kent State Friday. He ultimately popped back up and led the offense flawlessly. He will have to continue pacing UCLA's high-octane attack against Mick Cronin's strong, physical defensive unit.
