He's a fringe PS QB at this point the only reason we notice at this point is because of him being in the same draft class as Josh and his comments after getting picked.
Worst case scenario is an interception and a fumble/steal? and TD. Even if they some how ruled he intercepted the ball he never went down and Gabe took the ball from him in the endzone which is a TD.
Looks like they might be able to get CMC cheap, Barkley probably isn't even available. He's a leader in their locker room at this point they're not trading him while they're 4-1.
