With the way the season's gone, the conference bid can still go to someone other than Pitt, West Virginia, and UConn. But the most likely case is that one of those teams will secure the BCS berth
Losses by South Florida and Syracuse this weeekend likely have knocked those teams out of contention. Unless all three teams go 1-1 over their last two games and set up a huge three-way tie, it's probably coming down to Pitt, WVU, and UConn.
The easiest scenario for Pitt is obviously to win out. Can Pitt lose one of its final two games and still win the conference? Technically, yes. But it gets real confusing after that...especially if the loss is against WVU. If Pitt beats WVU and loses to Cincinnati, a UConn loss in one of its final two games would still send Pitt to the BCS.
A loss against WVU and a win against Cincy? Well, while Pitt might not be eliminated (I'd need to do the research), it would take a lot happening, including UConn losing a game and WVU losing the following week to Rutgers. Yeah, don't hold your breath.
But the Panthers can make this simple on everyone if they just win their next two games. With WVU looking very good defensively, that could be easier said than done.
