JG threw 82% of the passes that we threw as a team last year (JG 246 attempts, Chryst 51 attempts)I would say that contributed. I would also say he was nowhere near where a 3rd year QB should be in those things.
Sixth in sacks is not "putrid" and especially with a QB that either couldn't or wasn't allowed to throw hot reads to the short middle.... a QB whose best strength was long developing plays that didn't require him to think quickly or make good pre-snap reads.
I've never said that the OL didn't have issues. At times, those guys just looked stupid with missed assignments. Other times... they just got physically abused by mediocre DL's. But the whole notion that JG was nothing but a victim of their poor play is pretty ridiculous. He didn't help them.
JG accounted for 96% of the sacks as a QB last year (JG was sacked 22 times, Chryst was sacked 1 time)
Lots of reasons for that, some of which are not JG's fault. But he certainly appears to have some of the blame to me.
