The hard question is: what evidence have we seen that he is going to be any good? So far he looks like EJ Manuel 2.0, right down to getting badly injured on an ill-advised run.
In the first half I thought Josh was wandering into the Peterman Zone, where everything is going so badly that he panics into more mistakes. Hate to say it but Barkley looked like he has a better idea of how to play football.
