It doesn't seem so farfetched for this to happen. This assumes SMU is in. Of course, Syracuse needs to take care of business. If this were to happen...
ACC losses:
Miami 1 loss
Pitt 2 losses
Louisville 2 losses
Clemson 2 losses
Syracuse 2 losses
Pitt still has Clemson on their schedule so need a loss there since Pitt gets in over head 2 head.
Then the ACC crazy tie breaker rules kick in.
Man that Stanford loss stings...
