I'm not sure that Jake is the best guy, but the fact that you picked him to start the season means you stick with him in a game like today's game. If you make the switch in the first quarter (or any time in tonight's game) like so many armchair coaches wanted, then Bohannon struggles? You are toast the rest of the year with confidence issues at qb and a divided locker room.
When/if you make the change, you'd better not be willing to go back. You've got one chance to make the change. Tonight wasn't enough to make it yet
