Agree to disagree, it might be a slight exaggeration to blame it all on the OLine, especially given BF's play calling and Sargent's bad day, but you have to abandon the run when you're facing 1st and 30 due to holding penalties on the line. The same line that gave up 8 sacks. There were more opportunities to run it, especially given the success Young was having early in the 3rd quarter. But it's a tough call on 3rd and 3 to run it when your line has been getting shredded all game.
Also, I'll put it out there that Stanley's interceptions were nowhere near as bad as you might think and 2 out of 3 were in situations I'd want him to be forcing it. His first one was bad as he didn't recognize the coverage on Tracy and was hurried into a bad throw that never had a chance. The second one he was again pressured but had a decent enough throw despite being hurried into single coverage that it should have been at worst a 50/50 ball to Tracy, but never an interception, except Tracy allowed himself to be pushed off his path and the DB ran his route for him. Next year, or even later on this season, that will be a completion inside the 5 yard line. Finally, the last one, he was either going to take a sack or give it a chance forcing it on 4th down with no one open.
I do agree it should be flushed and the OLine should be significantly better after being humbled, but it's completely okay to single out a group and say it's mostly their fault. Ask yourself, if Stanley hadn't been sacked 8 times and hurried countless more, would he have thrown 3 picks? Also, as I mentioned in another post, I don't think it's the OLine's fault that they played so poorly. I think you can point a finger at the coaches, specifically Polasek, for not having them ready.
