With just three games left in the regular season, Clemson is still on the wrong side of the NCAA Tournament bubble.

With a middling conference record, a mediocre computer profile and now just one RPI top-50 win (and that's against No. 50 Boston College), the Tigers can't afford to play anything but their best basketball down the stretch.

A win at Duke would solve all of Clemson's problems, but that doesn't seem like a realistic possibility. So the Tigers will need to dispose of Wake Forest at home on Saturday and then knock off fellow bubble resident Virginia Tech at home next week to have any hope at an at-large spot in the tournament.

Even with a 9-7 conference record, Clemson would probably need two wins at the ACC Tournament to feel anywhere near comfortable about receiving a bid. It would then depend on their RPI and strength of schedule, which aren't very good at this point (RPI: 65, SOS: 88).

It would also help the Tigers' case if they look good in comparison to other ACC bubble teams at the end of the season. They have a head-to-head win over Boston College and a head-to-head loss against Maryland, so those wash out to some extent. A win over Virginia Tech would help their case when being compared with the Hokies. The committee would also be more likely to reward a deep ACC Tournament run by the Tigers if other teams lose early in the tournament.

A 9-7 ACC record was enough to get Clemson a No. 7 seed in each of the past two NCAA tournaments. This year, that record alone won't even be enough to get the Tigers into the dance.
