Man, he didn't have a chance to throw it away on a lot of those... I get to watch the game here and his offensive line was pushed right back into him (when they managed to touch somebody) so he couldn't step into throws.
No running game, down 3 OL, lost 2 more during the game, and the ones who were out there looked pretty bad.
But, yeah, Carson looked way off on a lot of throws after looking perfect for most of the first half... except the one that Ertz dropped on 4th down. His throwing motion looks a little long too.
