Most people in the media that rate QBs rate them with a odd set of criteria. I base my ratings off data and watching the dude play with combine numbers helping to finish the eval off.
Murray is small. However, he is tremendous throwing the ball in the pocket and has one of the lowest batted passes number. So, to me the kid shows size doesnt matter for him. But to the media evaluators it matters.
Murray did not dink and dump the ball. His Yards per Attempt led College Football at 11.6. Will Grier was 3rd at 9.7--and if you ever watch W Virginia that tells you something. Murray is making difficult throws, down the field with accuracy.
I would take Murray over all the QBs last year except Baker. Not taking Murray because you already have Rosen would be a colossal mistake imo.
