I think that JB is the ultimate backup QB to Luck. Having said that, it is logical that JB should start this Sunday and get in game shape ASAP. If he gets 5 plays down that means there are 5 plays that the offense can run versus 100 that they can't with Tolzien. JB has size, arm strength and mobility that Tolzien lacks. There is no tapes on JB with a Colts uniform and that is another factor which will keep the Cardinals guessing what to expect. If we are lucky and he produces a win, that will generate tremendous confidence throughout the entire team and organization.That is how I see it. Now let us wait and see what Pagano decides who starts.
