I think if they played in the Big 10 they would be a 4-4 to 5-3 type team. The reason those teams are dangerous in bowl games is because the whole team believes in the system and what the coaches teach because it got them W's. When you win, everyone buys in, even if it's against sub-par competition. They also have the best athletes usually in their respective conference. A team that buys in, has decent athletes and accustomed to winning is going to be a dangerous bowl opponent.
Lickliter's system worked.. no question. But it worked because his teams at Butler bought in because they won a lot of games with that system. It wasn't working at Iowa though and the players didn't buy in.
Boise St plays in the Big 10 they are going to lose some road games, they are going to get injured more, and they are probably not going to have quite as strong team unity.
