First point is: give the guy a giant target who can catch and outrun everybody (can't be covered), and EJ might find a comfort zone. I am not saying he isn't missing open receivers, but he's basically outfitted with two smurfs, SJ, Chandler who is fine when he isn't dropping the ball or getting penalized, and running backs that the OC refuses to call passes to.
To your point: No, but it's no less likely that this QB is a grower and needs some time, especially in light of injury. Either way, we'll find out.
