Not that every injury is the same, but torn pec is what ultimately forced Mayo into retirement. If you don't come back 100% from it, it's a tough one to deal with for a guy who has to tackle a lot. But if they don't even few it as season ending, might not be as bad. Still, something in the back of my mind for him. I wish him the best, he's a great player.
I don't have any definitive thoughts on this game until we hear more about Mac. But in general, I think the defense will hold up fine against Pitt. Offense needs to finish drives and not turn the ball over. And I'd love to get Bourne back into the swing of things. Without Thornton (unproven though he is yet), he's out more explosive athlete on offense.
