Joe did fairly well at the end of that game. I don't think anyone would argue that. The first half of the Montana game, was horrendous. If I recall... a throw into the ground, overthrew an open receiver by 10 yards, nearly threw a pick six, followed up by the fumble debacle play.
We've seen one half of Bartels play this year. Comes in stone cold, not seeing real game action for a year, gets his composure after a couple of possessions, and marches the team down the field twice, spreading the ball around, for touchdown drives.
I doubt Joe will lose his starting job in this way. But I hope his leash got a lot shorter after we have seen we have a backup capable of running this system.
