Way too many variables that aren't quantified in order to have a true assessment. The explanation about the Cobb throws in particular stands out to me...on two of those TD's, he checked to that play based on the man-look he saw pre-snap yet they were graded as a 0 because the throw was an easy one. That throw would never have happened if he doesn't check to that call. That's just one example and it applies on so many plays for multiple quarterbacks.
