How long do you think it takes a QB to be comfortable with the game? Some want to start rookie qb's right away and see if they can handle the fire. Others prefer to sit them 2 or 3 seasons. I ask this b/c I see so many people wanting to get rid of Carr but regardless of how you feel about him prepping a new QB takes time. Even Grossman playing in the superbowl has been in the league a bit and is still all over the place at times.
