Wisconsin has gotten insanely lucky on all major coaching hires for like 30 freaking years. They're due to miss eventually.
The most staggering thing is how badly they got beaten on the lines on Saturday. They sure didn't look like Wisconsin, but all that said, if I were them I'd be content rolling with the punches and just try to get that line good again. If you get that line good, get a decent TE and then get lucky with another Russell Wilson type transfer that team would be set for a helluva run. You can't really philosophically change what you do if you are Wisconsin because Madison is so far north and if you ain't got lines and a run game, your goose is cooked in November.
