Clemson hosts Louisville and goes to Virginia Tech and Pitt. Clemson will lose at least one of those games.Pitt can definitely remove SMU or Clemson (or both) from consideration and make the above scenario obsolete. I think the scenario above was only selected because of those 3 teams not playing each other. If Pitt and Miami both go unbeaten in the regular season, its a lot more straightforward.
On the flip side, if Pitt goes 1-1 against Clemson and SMU and wins out otherwise, the team that beats Pitt picks up a conference L elsewhere while winning out otherwise, and the team that Pitt beats wins out otherwise, and Miami loses one, its even more anarchy than the above scenario. 4 teams with a single conference loss. Miami would play none of the other 3, Clemson / SMU would only play 1 of the other 3, Pitt would have played 2 of the other 3. There’s no good way to clean that up.
SMU goes to Duke, then hosts Pitt and BC (going to UVA will be an easy win because UVA is soft). SMU will lose one of those three games.
Pitt has the toughest schedule remaining: at SMU; hosts Clemson; at Loiusville; at BC (hosting UVA will be an easy win).
I think Miami will remain undefeated. I'm hoping Pitt will win out to make things exciting (two undefeated teams).
However, Pitt typically has at least one horrible game each season where they unexpectedly lose a game.
