In my opinion, Jerry is better than the majority of fans give him credit for. He has gotten better since joining the team a couple years ago. He is a solid pass blocker, who at his best sets a nice pocket for Eli to step up into. After Pugh was injured, and with Richburg not playing particularly well, I actually thought Jerry was the Giants' best offensive lineman down the stretch.
This past season was Jerry's best season, because he has improved as a run blocker to the point where he is decent. He just doesn't seem have the aggression or explosion to be a consistently good run blocker, though.
What I wonder, and none of us can know, is if 2016 will be Jerry's career best. He is 30. I guess there is some chance that he will continue to improve, and have a late-career surge. But more likely is this is as good as he will get.
So I guess my answer to Dan's question is, yes, I think he's gotten short shrift from fans and media who just parrot the "right side of the line" cliché over and over, when since 2015, it's really been the tackle positions that have undermined the OL, while the middle of the line has been at least OK. However, I think they should definitely be looking to add talent at the guard position, though it is not the pressing need that tackle is.
