Pittsburgh won't be able to score with Washington. That pick is a little too trendy and I don't see it happening. Pitt typically can beat teams that it can shut down but not have to outscore (UConn, Syracuse, BC), but UW is one of, if not the highest scoring team in the nation of the big schools. No way will Pitt be able to keep up with them, because Pitt really struggles to put points on the board. I don't see it happening. Pitt is a dangerous team, but that's a bad matchup for them.
As for GT and Louisville, I'd probably take GT, based simply on how weak Conference USA is this year in my opinion. GT is such a jekyl and heide team though it's hard to say who will show up. It could easily go either way.
