My take is that some posters subliminally bought into the Russell Wilson-hype, which is unfortunate. Remember, they had a very weak non-conference schedule. When you buy into the media's propaganda, you are only giving them "more power than they deserve." If Wilson ends up as a 1st round pick (or in Kaepernick, Pat White, T-Jack, Armanti Edwards territory), he will fail anyways. So, nothing to worry about.
Also, if you watched Wisconsin in recent (televised) games, you would have seen them doing "cutesy, gimmicky plays" that really was a warning for the future against tougher opponents. It was there for those who were willing to see.
It's not that Wisconsin couldn't have defeated Michigan State, but, fact remains, they weren't going to "steamroll" everybody. Wisconsin did have a "competent QB" last year (even if the MSM wants to deny it), and what happened? They lost their Bowl Game to TCU, which shocked many people. So, I ask, why would Wisconsin somehow be "unbeatable" this year? They also lost two 1st rounders in J.J. Watt and Gabe Carimi...
