If your going to run a spread where the QB runs, he's got to do it more than a few times to be effective. Aspread is pass alot or you use it to open up the field and create better running lanes for the option and use the speed to slash the D. Take West Virginia for and example. Bill Stewart stated that he wanted Pat White to show off his arm more and early in the season that made one less thing the defense had to worry about. They finished the season strong because he let White start running. Now i know there are spreads where they pass alot, and that is effective too, Mike Leach and Texas Tech, he is a mad scientist. They use the running backs to take the LB's out of the middle of the field so they can run the crossing routes with guys like Crabtree. But when you have that at WR, it's not hard to see why they are that good. For me though, I would say you gotta run with the QB so the defense has to worry about another thing, the RB, QB, even the TE (florida with TE Hernadez) on the option and even the WR in motion. But then again CA, you have a good point, if you run the QB every now and then you could suprise the defense with a few draws. What I think is that the option can set up the run by spreading out the D.
