I found this interesting video from the coaches over at the BigTen Network. Of course a lot of things need to come into play when developing an offensive philosophy as a coach, including personnel, assistant coaches, the league you play in, and others.
I always like to use Steve Young, the great QB from BYU in college and the 49ers in the NFL as an example of having a QB who can excel in both offenses. Now Young never played in the modern day spread offense that uses the dual threat QB on designed running plays, but there is no doubt he would have excelled, just as he did in the West Coast Offense.
Keep spreading u'm!
