UNC tops among 'question mark' teams

The North Carolina Tar Heels are one of several teams that are tough to figure out. Anthony Nesmith/CSM

Don’t expect the roller coaster to end anytime soon in Chapel Hill. No one can figure this North Carolina Tar Heels team out -- not coach Roy Williams, not opposing coaches and certainly not me.

One night it’s a near-loss to Holy Cross, the next a setback in Chapel Hill to Belmont. Then comes a stunning victory over the defending national champion Louisville Cardinals on a neutral court, followed by a brutal showing at UAB and then two more top-15 wins -- one against top-ranked Michigan State Spartans and another over the young, talented Kentucky Wildcats this past Saturday.

Wins against Michigan State, Louisville and North Carolina. Losses against Belmont and UAB.

Williams needs a shrink for these guys. He may need one for himself. That's why the Tar Heels lead our look at the biggest "question mark" teams in the country -- the teams that could still go either way.
