What if Carr just isn't in sync with the rhythm of Pete's playcalling. For instance how many times have we seen Pete call shot plays on 3rd down and short?
More than that, if Carr is uncomfortable in the pocket it's because Pete has made him that way. It started out with the offensive line being an issue, but that has improved.
When Carr is comfortable and in rhythm and feels good about his game, he calls his own shots. However, when you have Pete forcing plays, putting the offense in bad situations then asking Carr to bail them out on 3rd and forever, you can see why the guy is skittish. After that week 4 game i literally said aloud, if Pete keeps calling plays like this he's going to get Carr killed and to date we've learned he has 3 broken ribs and 2 concussions this year alone.
Pete's getting him lit up like he's Kurt Warner in a Mike Martz system.
