Top 5: The best upcoming college hoops games

• Top-ranked Indiana meets upstart Butler, a team now in the Atlantic 10 and playing a rigorous non-conference schedule
• No. 5 Florida faces No. 8 Arizona in a battle between two ranked teams
• No. 6 Louisville has a chance to be upset when the Cardinals play Memphis

It's another jam-packed Saturday full of college hoops highlighted by two Indiana schools bumping heads (Butler-Indiana) and culminating with a clash between two top-10 opponents (Florida-Arizona). Here's a look at the top five games on deck for Dec. 13-19.

No. 1 Indiana vs. Butler | Saturday, 2 p.m., CBS

About the Hoosiers (9-0): Losing role player Austin Etherington for the season with a broken patella doesn't make life easy, but the Hoosiers still have the makeup of the nation's top team even if their résumé doesn't stack up to No. 2 Duke. Player of the year candidate Cody Zeller (15.4 ppg, 8.9 rpg) leads five Indiana players averaging in double figures. Zeller is coming off his second double-double of the season with 19 points and a career-high 19 rebounds in a win against Central Connecticut State.

About the Bulldogs (7-2): Butler has impressive wins against Marquette and No. 18 North Carolina. The Bulldogs didn't fare well against another Big Ten team, No. 10 Illinois, in the Maui Invitational in a 78-61 loss but beat Northwestern 74-65 on the road. Arkansas transfer Rotnei Clarke (17.3 ppg) has steered Butler's offense and will be a tough matchup for Indiana.

The matchup: The Indiana schools will meet at Century Life Fieldhouse in Indianapolis, home of the Indiana Pacers, rather than on either campus. Indiana has non-conference wins against ranked opponents North Carolina and No. 21 Georgetown, but a win against a tough Butler team can prove the Hoosiers are still strong despite the injury bug. If Zeller stays out of foul trouble, Butler won't be able to handle Indiana's size.

Our pick: Indiana

No. 6 Louisville at Memphis | Saturday, 2:30 p.m., FSN

About the Cardinals (8-1): Rick Pitino scheduled tough, as the Cardinals played Missouri and Duke (Louisville's lone loss) and strong mid-majors Northern Iowa and Illinois State. A win won't come easy on the road against Josh Pastner's squad. Russ Smith has been a pleasant surprise for Louisville, averaging 20.3 points through nine games, and Peyton Siva (10.9 ppg, 5.7 apg) continues to direct an offense that often has lulls. The defense wins games for this team, but its inconsistent offense could be troublesome.

About the Tigers (6-2): Convincing wins against mid-majors Austin Peay, Ohio and Tennessee-Martin have helped Memphis get back on track after early losses to Virginia Commonwealth and Minnesota. Geron Johnson was suspended for the first three games, but his return has aided a revival. Memphis is balanced on offense with seven players averaging more than 20 minutes and eight points a game.

The matchup: Louisville looked vulnerable against Northern Iowa and Illinois State, and this is the team's first road test. Major upset potential here. This is a perfect chance for Memphis to sneak back into the top 25.

Our pick: Louisville

Belmont at No. 9 Kansas | Saturday, 7 p.m., ESPNU

About the Bruins (7-2): Belmont has started strong heading toward the start of conference play in its first year in the Ohio Valley after switching from the Atlantic Sun, and the Bruins should challenge Murray State. A win at Stanford and a respectable loss to VCU likely won't be enough from the non-conference schedule to earn an at-large bid. A win against Kansas could turn the tide. Ian Clark (18.9 ppg) and Kerron Johnson (14.2 ppg) form one of the most underrated backcourts in the country. Clark shoots 56% from three-point range.

About the Jayhawks (7-1): A 67-64 loss to Michigan State in November is the team's lone blemish. A 90-54 demolition of previously ranked Colorado shows what this Kansas team can do on its home floor. Freshman Ben McLemore (16 ppg, 5.6 rpg) has fit in nicely with the veteran trio of Jeff Withey, Travis Releford and Elijah Johnson.

The matchup: Belmont lacks size and can sometimes make up for it with steady guard play, but playing a top-10 opponent on its home floor with a savvy 7-footer will expose the Bruins. This should be another blowout for Kansas, but if Belmont's guards are hitting, it might be close.

Our pick: Kansas

Kansas State vs. No. 14 Gonzaga | Saturday, 9 p.m., ESPN2

About the Wildcats (7-1): Aside from a loss to No. 3 Michigan, Bruce Weber's first season in Manhattan has started well. A matchup against the Bulldogs will answer more questions about this team's potential. Guards Rodney McGruder (12.9 ppg, 5.6 rpg) and Angel Rodriguez (10.5 ppg, 4.5 apg) have driven the offense for a veteran roster that returned four starters from last season's 22-11 team.

About the Bulldogs (9-1): Gonzaga's loss to Illinois at home last week led voters to hit the brakes on declaring the Bulldogs a top-10 team, but this remains a highly efficient team that leads the country in shooting percentage (.527) and features six players averaging more than eight points a game. Elias Harris (16.6 ppg, 8.0 rpg) has NBA talent but will need to be more of a go-to option. Sophomore guard Kevin Pangos (10.5 ppg, 3.7 apg) has yet to catch fire this season, too.

The matchup: Gonzaga didn't fare well against Weber's old team and now follows it up with its first major road test of the season. That Illinois loss might be more of a testament to how good the Illini are, though, and this is a perfect opportunity to rebound for the Bulldogs.

Our pick: Gonzaga

No. 5 Florida at No. 8 Arizona | Saturday, 10 p.m., ESPN

About the Gators (7-0): Florida has looked dominant, but this will be only its second game in December (a 72-47 crushing of Florida State on the road was the other). A long layoff could make for a sluggish start for the Gators against their toughest opponent to date. Still, Billy Donovan's squad is a difficult matchup for any team. Kenny Boynton (14.4 ppg, 4.1 rpg) and Erik Murphy (11.9 ppg, 4.6 rpg) lead a potent offense that has won every game by double digits.

About the Wildcats (7-0): Arizona has looked impressive but has no wins against top-notch teams. Forward Solomon Hill (12.3 ppg, 5.4 rpg) was expected to be a catalyst, and Xavier transfer Nick Johnson (13.6 ppg, 3.7 apg) has meshed well with Mark Lyons (13.4 ppg) in the backcourt. A win could mean a lot for seeding purposes in March with the rest of the Pac-12 Conference struggling.

The matchup: They saved the best for last Saturday. Both teams are undefeated and have started off hot, so this will be a premier showdown. Florida appears to be the better team, but a two-week layoff isn't the best tuneup for a road game against a ranked Pac-12 team.

Our pick: Florida
