Great job citizen Cain, love real data to drive good analysis and accurate conclusions
Just a few thoughts/observations:
The guy with the best record above EJ also had the lowest amount of passing yards.
The HOF lock above EJ, Tom Brady, was also at the lower end of the passing yards (of those above him)
Conclusion 1 => Solid running games help young QBs tremendously
One other thing, it appears to me (from this chart, and the eyeball test) the biggest thing EJ needs to do to improve his game, is his throwing accuracy. Even just a 5% increase in that, would jump his productivity and success rate. That 5% would put him among the elite on this sample.
So, in real numbers, how many passes is 5%? In a conservative offense, that throws on average 20 passes a game, a 5% comes out to: ONE (1) more completing a game! In a more typical range - say 30 attempts per game - just 2 more completions would jump a 58% passing rate (aprx. 18/30—rounding up) to 66% (20/30). In an aggressive passing offense - 40 attempts per game - 58% is 23/40, 3 more completions gets it to 66%. Etc., etc.
My point: he is close. And the difference is not huge, and certainly doable.
Yes, 1) I am trying to find the positive, and 2) there are many other factors; but, in just pure statistical completion percentage numbers, just a few more per game will make a huge difference. No doubt, the real test and statistic that matters most is, "Wins" - I see him as very close to making a big jump in completion % and wins.
For me, that gives hope.
GO BILLS!
