Chip's offense isn't predicated on the option at all though. At its core, it's really just a sped up west coast offense, where you do quick, 1-read plays and up the middle runs, with the hope that you either break off a big play and/or wear out the defense. Except he sacrifices clock management to tire out defenses more quickly. Bradford is perfect for that kind of offense, as is Murray, because they're able to react quickly and effectively, and they have experience running it (albeit more slowly) at OU. Running the option adds nothing to the offense, except maybe an 8 yard play once or twice a game. You're not going to get huge plays very often in the NFL.
