@Rouxble already told you that he was 17th in DVOA
He was 17th in EPA/Play
He was 17th in Adj. EPA/Play
He was 17th in ESPN QBR (which is basically EPA adjusted for situations)
I want to say he was 14th in DYAR (but I can't remember where I saw that).
And how am I cherry picking? I just gave you where where he stood the first 13 games of the season and then showed you the last 4, which confirms my stance. We are only having this conversation because the last 4 games of the season practically doubled his TDs, added 1k yards, shot up his completion percentage, and his passer rating. The end.
I'm not saying that this is not something that we can't build on but 4 games shouldn't erase 13, although history shows that it do (for some).
