Well Jones is still their starting QB. So I am not sure how that isn't still a problem.I think the Giants OL is underrated, they aren't good or anything, but I don't think they are bottom 5. They are a better run blocking line than they get credit for. Only 12 teams averaged more YPC than the Giants last year, and that was without Barkley. Some of the pass blocking woes, I think, can be chalked up to Daniel Jones not getting rid of the ball, often because nobody was open, which may not be a problem this season.
That is probably low for the Vikings as well, though I guess its likely assuming with 2 rookie starters, they may not gel instantly. Say what one will about Reiff, he was pretty consistent, if unspectacular.
I'd personally argue the Steelers have the worst OL.
Reiff was solid. I consider him a plus for the Bengals line this season.
