Kind of a 1a conversation. Go back and look at the first or second catch by Gray. He gave up on the route, slowed down, Fitz threw him the ball and he caught it by luck. This has happened several times this year with all receivers.
As for him over throwing, that is on him. He is not setting his feet. The coaches can tell him this all day long but until he spends hours by himself visualizing experiencing situations where the pocket is less than ideal, he'll never connect on the long passes.
The run reads come with reps with current personnel . I wish that Dan would work Lee into some games to get some game experience. Trying to costantly tackle white Relf, Williams or Lee would get old for second level guys.
I see tons of potential but it is up to fitz to put the work in to be great.
