What often muddies the waters is that the kids who are playing QB in HS are usually by far the best athlete on the team. Not necessarily the best player by position, but best athlete. I've seen it so often, and know how it can actually backfire against a coach in college. A battle for playing time can end up an exodus of talent, and a problem getting guys to join your program down the road.
Wisconsin plays run first, pass when necessary. That's their game. That means that you don't need a guy at QB whose pedigree is that he can't miss. What you need to do is bring in a few athletic QBs and find one who can play the game well enough at the position that his work can complement the running game the Badgers employ. Even if some of the QBs you bring in are total duds, some of them can become WRs, DBs, and TEs. We've seen this often at Wisconsin.
Tyler McEvoy is a prime example of a QB who moved to WR, and then DB. He made honorable mention All Big-10 his Sr year, and did end up playing in the NFL.
The trick is finding that guy with just enough talent. Whatever Wisconsin is doing wrong in getting QBs, a hell of a lot of them end up somewhere in the NFL, at least as back ups.
