If it is "too close to call" please go with the younger player that has 2 years of eligibility and not just a one year rental. We saw improvement from game 1 against WV to game 3 & 4 agains OU and OSU. He will get better. He seems to have fixed his turnover issues per ARod.
Then please use Gerry Bohannon in an NFL Taysom Hill role. Let him line up in weird formations to confuse the defense. Take advantage of his running ability (he was a running back early in his High school career). Let him throw some "surprise" passes.
