College basketball schedule and scores: Five top-25 showdowns headline huge Saturday

All times Eastern

No. 20 Duke at No. 18 Louisville (12 p.m./ESPN)

The Blue Devils have knocked off three consecutive top 20 teams, but their already thin 6.5-man rotation (sorry, Chase Jeter is now down to 5.5 without Matt Jones). Jones played the largest role of anyone in holding Louisville's leading scorer, Damion Lee, to just 3-of-15 shooting from the field in a 72-65 Blue Devil win at Cameron Indoor 12 days ago.

Florida at South Carolina (12 p.m./SEC Network)

South Carolina suddenly finds itself in the midst of its first losing streak of the season and now needs a win to avoid starting the final week of February with some serious NCAA Tournament bubble talk. Florida has won seven straight games in this series.

No. 8 Xavier at Georgetown (12 p.m./Fox)

Georgetown is the only team this season to beat Xavier at home, but the Hoyas have gone just 2-6 since that seemingly monumental victory back on Jan. 19. The Musketeers, meanwhile, have won seven of their last eight.

Saint Bonaventure at No. 15 Dayton (12 p.m./NBC Sports Network)

The A-10 has one of the more interesting regular season title races in the country, with Dayton, Saint Joseph's and VCU all entering the weekend with two conference losses. The Flyers may have to find a way to keep pace with the other league leaders and extend their home winning streak to 21 games without third-leading scorer Kendall Pollard, who has been sidelined recently with a lingering knee bruise.

No. 11 Miami at No. 5 North Carolina (1 p.m./CBS)

The ACC standings tell you all you need to know about the importance of this one.

Army at Navy (1:30 p.m./CBS Sports Network)

One of the cooler developments this college basketball season was Madison Square Garden hosting an Army/Navy women's and men's double-header for the first time last month. Unfortunately, the unforgiving winter weather that hit the city forced an evacuation of MSG immediately after the women's game, news which kept the men from being able to play inside the world's most famous arena. The Navy players, who had so looked forward to playing inside the arena, came onto the court and pretended to perform a pregame layup drill despite not having any basketballs. The Midshipmen eventually won the rescheduled first meeting (played at Army) by 14, and have won five straight games in the series, the longest winning streak for either team since 2002.

No. 25 Baylor at No. 24 Texas (2 p.m./ESPN)

Cracking the Baylor zone and finding a way to defend Taurean Prince are the two biggest keys for Texas in its quest to sweep the season series with the Bears.

Pittsburgh at Syracuse (2 p.m./ESPN2)

It's a matchup of two ACC bubble teams that didn't exactly play with a great deal of urgency earlier this week. Syracuse looked almost lethargic in a 14-point loss at Louisville, while Pitt needed double overtime to pull off an ugly home win over lowly Wake Forest.

Saint Joseph's at Davidson (2 p.m./NBC Sports Network)

Saint Joseph's is the lone team in Division-I yet to taste defeat on the road. To end that streak, Davidson will likely need a healthy Jack Gibbs, who enters the weekend leading the A-10 in scoring at 24.9 points per game. Gibbs and a pair of other Wildcat contributors missed Wednesday's win over Richmond due to illness.

Mississippi State at Alabama (2:30 p.m./SEC Network)

The Bulldogs will be looking to break the hearts of an SEC bubble team for the second time this week.

Butler at No. 1 Villanova (2:30 p.m./Fox)

The top-ranked team in the land has won 36 straight games at home, and ranks fifth nationally in defensive efficiency and 15th in offensive efficiency. Jay Wright's team, which will celebrate senior day on Saturday since the Villanova students will be on Spring Break for the final two home games, is 19-0 this season when holding opponents below 70 points.

Florida State at Virginia Tech (3 p.m./ACC Regional Networks)

There's no such thing as a "must-win game" in college basketball unless a loss literally marks the end of the season for the team in question. Don't let anyone ever tell you any differently. That said, this one feels awfully close to a must-win for Florida State's chances of landing an at-large bid to the big dance.

No. 3 Oklahoma at No. 10 West Virginia (4 p.m./ESPN)

Oklahoma's surprising loss at Texas Tech earlier this week leaves Kansas alone atop the Big 12 standings heading into the weekend, with West Virginia a game behind and the Sooners (as well as Texas and Baylor) two back. A third straight loss for Lon Kruger's team would put its chances of earning a No. 1 seed in the NCAA Tournament on life support.

Connecticut at Cincinnati (4 p.m./ESPN2)

UConn is coming off perhaps its biggest win of the season over No. 21 SMU, while Cincy is reeling a bit after a heartbreaking overtime defeat at Tulsa. The two linchpin programs of the AAC now square off in a game both could really use to solidify their postseason resume.

Illinois State at Northern Iowa (4 p.m./CBS Sports Network)

Northern Iowa turns into the Warriors when it faces good to great teams, which probably isn't good news for Dan Muller's solid Illinois State squad.

LSU at Tennessee (4:30 p.m./ESPNU)

Despite their high standing in the SEC and their claim on (rightly or wrongly) the most talked about player in the country, LSU's 10 losses and RPI of 81 make it far from an NCAA Tournament lock at the moment. This is the type of game the Tigers have to have if they want to feel comfortable four Sundays from now.

No. 2 Kansas at Kansas State (6 p.m./ESPN2)

Kansas has won an unreal 50 of its last 55 games against Kansas State, but the Jayhawks are currently riding a two-game losing streak on the road in the Sunflower Showdown for the first time in more than three decades.

No. 14 Kentucky at Texas A&M (6:30 p.m./ESPN)

Texas A&M is 14-1 at home this season, but the Aggies are still reeling a bit after losing four of their last five, a skid that took them from the nation's top five to out of the rankings entirely in just three weeks. To regain some national respect, they'll have to take down a surging Kentucky squad that has looked like a legitimate national title contender during its current four-game winning streak.

TCU at No. 13 Iowa State (7:30 p.m./ESPNU)

The losses are suddenly piling up for Iowa State, which suddenly finds itself out of the Big 12 race and could be out of the top 25 entirely if it doesn't get back on track against league cellar dweller TCU.

No. 19 Notre Dame at Georgia Tech (8 p.m./ESPN2)

The nation's most efficient offense will be on display against a Georgia Tech team riding high after a surprising road win over Florida State earlier this week.

No. 17 Purdue at No. 22 Indiana (8:30 p.m./ESPN)

The on-court rivalry is cool and all, and this game has the potential to be an extremely entertaining one, but I'm more focused on the Crimson Quarry/Hammer and Rails Twitter rivalry.

Texas Tech at Oklahoma State (9:30 p.m./ESPNU)

Two weeks ago, Texas Tech was 3-52 in its last 55 games against ranked opponents. Since then, the Red Raiders are 3-0, with wins over No. 14 Iowa State, No. 21 Baylor and No. 3 Oklahoma.

Saint Mary's at Gonzaga (10 p.m./ESPN2)

Not only is this one of the more underrated rivalries in college basketball, but this is a massive game when it comes to Gonzaga's hopes of extending the nation's fourth-longest consecutive NCAA Tournament appearances streak. The fun simply doesn't stop on this Saturday.

Oregon State at No. 16 Oregon (10 p.m./Pac-12 Network)

Your token GP II:

Colorado at UCLA (11 p.m./FS1)

UCLA has lost three of its last four games at Pauley Pavilion, and a loss to Colorado on Saturday would guarantee the Bruins their first non-winning season in Pac-12 play since 2010.

Hawaii at UC Irvine (11:30 p.m./ESPNU)

Did you know Hawaii is 21-3? Because Hawaii is 21-3. Watch them battle for first place in the Big West against the nation's tallest team.
