How Did Their Systems Affect Them?
My goal here was to take out the variability of systems they all played in. Thus, how would Derek Carr have performed in an average system? This is imperfect, but it gives you a feel for how the systems helped or harmed them.
What I’ve done is taken out drops and then used the data to create an average system. The result is what their overall completion percentage would have been if they had played in an average system and the difference between the actual and adjusted completion percentages.
- As noted earlier, Mettenberger threw deep far more often than what is expected of college QBs. If he had capitalized on his higher accuracy in the shorter zones he would have seen an increase in his total accuracy.
- On the other hand, Boyd’s system was far more favorable to him. The high percentage of screens and high percentage throws gave him an overall advantage relative to what is expected from other QBs. In total, his completion percentage would have dropped 3% in an average system.
Below you can find a target chart for each QB detailed here. The graphic shows the location of each target for the quarterback broken down into individual spots on the field. The bigger the circle, the more passes a QB threw to that spot. The colors signify accuracy, the brighter red – the hotter or more accurate the QB was. The more blue spots represent cold or less accurate areas.
The charts don’t give you any statistical insight, but are there to give you a feel for how the QB did throwing to certain areas. IE…how often did AJ McCarron throw outside the numbers or where were Mettenberger’s deep passes located.
