I don’t think he plays too tight at all. To me, it looks like he’s way too relaxed, like a game isn’t going on and they are still at practice. Slow to get to the line, he barely moves in the pocket and waits too long on his primary target, then when the play breaks down it’s like he’s just trying to get the play over with instead of making something happen.
They rarely show him talking to his teammates on the sidelines during the game. He just sits on the bench waiting to go back in.
I think the guy has all the athletic tools, he just not a baller.
