its also worth reiterating (iterating (?)), this is his 2nd yr in the league, first with an actual offense that is coherent and hes been asked to significantly change his game (under center vs gun).
last year probably set his development back, this year is ahead of schedule.
his receivers frequently do not help him, like really bad drops. even with that, if this years stats are viewed through the lens of dont turn it over and dont take sacks, then mission accomplished (and thats not including wins).
