Five undefeated teams remain in NCAA Division I but each of them face a brutal stretch of games over the next two weeks. Which team has the best chance of going down first?

5. Duke » It used to be the non-con schedule that was a cakewalk. Aside from Maryland, now it's the ACC. The top-ranked Blue Devils still need to get through a tough visit to Florida State on Wednesday, but their biggest challenge could come against St. John's at Madison Square Garden on Jan. 30.

4. Ohio State » Like Duke, the second-ranked Buckeyes face a stiff conference road test Wednesday at Michigan, which took Kansas to overtime. If Jared Sullinger (10.3 rpg) can control the boards, it'll be Jan. 22 at Illinois or Jan. 25 vs. Purdue before OSU get its first loss.

3. San Diego State » Kawhi Leonard and the Aztecs are college basketball's best story but the fairy tale ends in the next two weeks. If UNLV doesn't do the job on Wednesday, Jimmer Fredette and BYU ensure that midnight comes on Jan. 26 for this Cinderella.

2. Kansas » The pressure is on after the Jayhawks barely survived in Ann Arbor. But with how tough they are to beat at Allen Fieldhouse, a Jan. 17 visit to Baylor might be the only thing between them and a perfect record heading into February.

1. Syracuse » The Orange are just hoping to survive their next stretch of Big East games because winning them all might be near impossible. They visit a surging St. John's on Wednesday before hosting bounce back-minded Cincinnati on Saturday. If Kris Joseph & Co. survive, a Pitt-fall awaits at the Panthers on Jan. 17.
