It's the evolution of the athlete. Look at RG3. About 10 years ago he would be a WR not a QB, unless he went to a full on triple option team. The man has world class speed and is a QB!!! As players get bigger, faster, stronger, they are put into different positions. Most of these spread QB's would be WB's, or WR's, not QB's. Plus that's what these bowl games want offense. Barely anybody watches them, so they need a hook. The rules give the offense an advantage so they are going to run with it. If you want defense watch the BCS title game. Of course most people hated the first game and have not been to kind to the rematch, but we'll see.
