With the NCAA tournament's field of 68 trimmed to 16, Insider's Jay Bilas, Joe Lunardi and Fran Fraschilla weighed in on five burning questions facing the remaining tourney teams. Topping the list: Will North Carolina get to the Final Four in New Orleans without a healthy Kendall Marshall?

Q: Are the North Carolina Tar Heels a Final Four team if Kendall Marshall is out?

Jay Bilas: Yes, but it is very unlikely the Heels can make it to New Orleans. If Marshall is unable to play, it is a crushing blow to North Carolina's aspirations to win a national championship.
