Reeves is McNair's consultant, not Dom's tip hotline. I seriously doubt Dan tells Dom much of anything as it pertains to game planning.
Carr is a prototype QB who is tough, with a big arm and can make all the throws. He also has a wooden style in the pocket and has a poor feel for the pass rush. He is a slow decision maker and tends to throw better when he is chunking the rock to someone standing still, sitting in a zone, or in the flat. I don't see that he is very accurate on passes other than hitches, come backs, slants and outs. Carr could be a late bloomer but with his lack of instinct and little to no innate feel for the game, I think his improvement over the next few years will not be big. I think he is a low level starter in the NFL but is no franchise QB.
