You realize Anderson won 11 games the year before Paul got there right? Not even being a hater, I just don't think he's that good of a coach and starting last year you saw with HIS players what he will be. Average
Gary Andersen was doing his best to alter the direction of the Wisconsin program, which did not sit well with fans or the Athletic Department, including Barry Alvarez. The in-state walk-on program was starting to dry (HS coaches were vocal about their displeasure of the way Andersen maintained relationships in-state), he was accepting commits that would never be admitted (part of the reason he left for Oregon State), and the structure of the roster (i.e. lighter OL, dual-threat QB) would never work long-term. There is a reason that Alvarez,
explicitly, said "Paul saved our program..." Sure, there is hyperbole at play, but there is little-doubt the direction that Alvarez knew the program needed to go and Andersen wasn't the best fit. He's talked about this at length. Simply, Chryst is a coach that understands the foundation that has made Wisconsin successful and has rebuilt the walk-on program (i.e. securing PWO commits with offers from MAC programs), replenished OL depth, and recruited kids that he can get into school. The only one that was ever denied admission was Jordan Stevenson, an Andersen commit.
Last season was total dysfunction at Wisconsin. Injuries decimated the Wisconsin defense (i.e. Garrett Rand, Isaiahh Loudermilk, D'Cota Dixon), Quintez Cephus and Danny Davis were caught in legal trouble, and there were rumors about Alex Hornibrook that helped contribute to his departure. These types of circumstances are, often, out of the coach's control, but can be fixable. Still, the Badgers somehow won eight games.
Don't think you're a hater, at all. Simply, as an outsider, you see everything from the macro-level.
