Even the best college basketball teams have massive question marks heading into the 2014-15 season.
Whom will the defending national champions rely on in the post, and whom will the runners-up play at small forward?
What happens if Duke's big man gets injured or is simply not as effective as promised? On the flip side of that coin, what if Michigan State's key players actually stay healthy this year?
Will a freshman start at point guard for Kansas? What will SMU do without the freshman who was expected to be its starting point guard?
We'll try to answer all of those questions and more as we address the biggest issue facing each of the top 20 teams at roughly the midpoint of the offseason.
These 20 teams are based on the composite rankings posted in late April by ESPN's Eamonn Brennan, CBS Sports' Gary Parrish, USA Today's Scott Gleeson and Nicole Auerbach, and B/R's C.J. Moore and Jason King. If you feel like your favorite team was unduly left off the list, blame them.
The following slides are listed alphabetically by school.
