I gotta respect the NFL. They have everything anlayzed down to how tall someone should be for each position and how long their arms are and how a guy needs to throw a a ball to be successful. Now they even have fundamentals to compare to on how someone is supposed to throw when running for their lives. I'm sure they have it down to how the release should be when getting tackled from the left vs the right or straight on. They leave nothing to chance.
Jay isn't perfect. But why don't we see what happens with a good OL, a good coordinator and a better game plan. I would think most of the work put into fundamentals didn't go very far last year as you actually have to plant, which he doesn't have to to do many times. If he can't get it done with everything fixed around him, he will probably be gone.
As far as fundamentals, the guy can be facing backwards and launching from his a$$ as far as I'm concerned. Make the completion and score points. Bottom line.
