They can't handle the physicalness
They are just not built that way, and I'm not sure they will ever be. If stanford was able to do that Bama would destroy them upfront. Stanford is no slouch, but they're not bama or LSU mean either. Oregon was calling for Bama before this. The problem is Bama guys can run with oregon guys and they are 20-30 lbs heavier.
I just don't think any West coast team can play that kind of football. the big 10 is big/physical enough, but too slow in most cases.
I don't think FSU can handle it either, but who knows. They look to have a really good team all the way around.
