Ignoring the complete uselessness of discussing which one would be more advantageous (supposing that it's necessary to pick one over the other), I would be shocked to see a rivalry that seems to have been encouraged by the staff suddenly decided between one over the other. Two heads are better than one, and I think it's a little derogatory to assume that a team can't handle having more than one "leader." What is so wrong with having some solid depth at QB? There's no logical reason to try and build it at every other position, but get terrified over a little competition at the helm. It's good!
Then again, this is all irrelevant until we hit Big XII play. So I'll hedge my bet that we stick with two.
As long as they both play well, I am happy.
