Agreed, except for the fact that if they had a week to prepare, they'd give JH the reps in practice and play him until he proved he wasn't up to it. Then they'd turn to SR through necessity.
NB. In the rush to crown a new QB, people seem happy to ignore that we don't see how these guys perform the majority of the time, instead focusing everything into the microcosm of limited game reps. It's like deciding if someone's guilty in a murder trial, while only reviewing 20% of the evidence.
