USCe may have the best player on the d line but LSU has the best line. LSU rotates at least 8 players on the d line.
I think USC has the guy with the most upside but definitely not the best guy right now. I would take both our DEs over Clowney right now because they play so much smarter. A lot of people have ragged on Mingo this year, but I'd bet that the coaches don't agree. Clowney seems to have the green light to wreak havoc all the time while Mingo and Sam are asked to play more team defense. Clowney will be the best of the bunch in the NFL though.
