If Martinez struggles (completes <50% of his passes, multiple INTs), I think you HAVE to give Cody Green the ball. If they really were that close in the fall camp, then Cody deserves a shot too. However, if the team is still up big despite Martinez struggling, let him work through his issues. I think as long as the game is in hand, you don't pull the QB. Say we're down at the end of the 3rd Q and TM hasn't done much of anything...go to Green and see what he can do.
Let's just hope Martinez plays lights out and this topic never has to be revisited. I would like for this team to have some stability at QB, regardless of who it is (and I'm a Cody Green guy).
