My bad. I could have sworn he had a pro style QB at Cinci or Central Mich who was more than effective.
Well in his 3 years at Cincinatti, Munchie Legeaux was the only real dual threat he ever put under center (in 2012) and he pulled him more than halfway through the season and switched to Brendon Kay. Kay could still run a bit, but just enough to keep a defense honest. In 2010 and 2011, Zach Collaros was his main QB and he only got 200-300 rushing yards per season.
The interesting thing, though, is that no matter what kind of QB he's had under center, they usually top out around 3000 yards total (though LeFeavor got 3400 and 3300 two years...he's been the exception thus far). To me (and I'm no expert, so don't take my word as gospel), that implies that Butch's system isn't really built for a statuesque pocket passer who is no threat to run. He at least needs someone who can keep a defense honest with their legs.
That makes sense to me, since his approach in many ways seems to be old school wrapped in a new age hurry-up-no-huddle style offense. Since Butch has been here, his strategy for winning games has mostly been to win the field position battle and control the clock and time of posession with tempo. He's been about 55-60% run heavy at every coaching stop pretty much. It's easier to control the clock and win the field position battle if you've got a strong run game. Having a QB who can run, at least a little, helps in that regard.
Honestly, I don't expect to ever see a 4000 yard passer in this offense. That doesn't mean we can't be successful or have a great QB. I just don't think our coaches have much of an air-it-out philosophy.
Not that that couldn't change if we got the right QB and all. But history hasn't really set a precedent for it in Butch's other stops.
