Averages are skewed by outliers, such as Tua with an insane 200 qbr. Median is probably better and he is right there in the 4 important categories - 8th in QBR, 5th in YPA, 8th in completion%, 3rd in td/int.
Also, many of those categories are so meaningless it is laughable you would include them. Assuming not an analyst by trade. Do we need to rank if he an average number of attempts?? completions? Rushing attempts? wtf?
Not well above average (in the league, is that the comparison or nationally? idk), but right there in the middle with 2 years to improve and the worst ol in the conference.
