If I'm Warner, there are a couple of reasons that make transferring pretty sensible. First, if I am really a coach in waiting, learning from multiple staffs is always a good thing. You pick and choose the things you like and put them into practice once you become a coach. Second, if he really wants to play this year, then Nebraska is not going to be a good fit. He's been passed up, and it's possible if not likely that he's going to move further down once the dust settles after spring. Football is a really hard sport if all you do is practice, because practice sucks. He may still try to walk on at another P5, but if he does, I'd be shocked if he gets on the field much.
