Completion percentage is TRICKY..lol. According to SISDatahub, Carr and WInston are identical from behind the line to 10 yards, Jameis has a better completion percentage from 10-20, and Carr has a better completion percentage in 20+ yards. Due to the increase of "dink and dunk" QBs, completion percentages were skewed and that's why they began to try to formulate things like CPOE. We are judging the completion percentage between one QB whose career average depth of throw is 10 yards per throw to another QB whose career average depth is 7.5 yards. Whether fair or not, they are view equally in the eyes of most.
