The vulnerable No. 1 seeds

The Field of 64 is set. The NCAA selection committee didn't throw any major curveballs this year, offering few surprises beyond the inclusion of St. John's and the exclusion of LSU. As much fun as it is to complain about the committee's choices, this is all for the best. We can focus on this weekend's matchups without too much fretting over what should have been.
Anyway, there will be plenty of drama on the field. Several of the schools selected as hosts are only marginally better than the ones travelling as No. 2 seeds, and a surprising number of teams given a No. 3 seed are upset threats as well. Let's look at four regionals where the outcome is most in doubt.

Clemson: Three solid contenders

Given my druthers, I'd have given the Tigers the ACC's third national seed. Instead, the committee handed them what might be the toughest assignment of any regional host. Headed to Kingsmore Stadium are both Connecticut and Coastal Carolina, two teams in the top 20 of the College Splits power rankings.
