Honestly, I think that USC was over-rated. Once #11 went out, it was going to be almost impossible to do much of anything.
I think Gateway has one nice kid coming back, a DE and OL I think. Marques something. Also, a transfer LB is eligible now. From what I know, the rest of the kids are pretty much typical high school lineman. Larger kids that aren't real athletic or undersized kids that can move. I think P-R should have a definitive advantage up front on O and in the front 7 on D.
You mentioned this and I agree. South Fayette losing to CV is a huge upset in my book. I heard it was a clean game and CV just beat them. Maybe an off night, but SF reminds me of P-R when they went from 2A to 4A in 8 years time. Great team in 2A and 3A. Mediocre in 4A for a while. But SF has some good coaches and its a long season, but a surprising game nonetheless.
BUT, the biggest upset was CMac coming from 17 down to beat Lebo. I don't know how that happened, but CMac has been getting better. Played PCC respectable last week (PCC also down - Norwin had them within a TD...) You may know better than I since you live in the south hills, but I have to imagine the Lebo parents aren't real happy right now. Had always heard their Junior class was the class to get them over the top. Seems like they are going in the wrong direction. But again, its only 1 game.
