I understand your points, but the Giants were good last year and he got a huge contract for his play. He had much more time and didn't have to scramble for his life on every play.
There was one play last night early. Maybe the second or third series and Jones didn't see the guy coming from his blindside. Not not that sack from the cornerback who had that monster game. Much earlier than that. Probably a miss by the offensive lineman.
