We should just name this LT sack testing the "Michael Oher test". He seems to show up high on this list every time.
I did another midseason sim (this time with CAR) to check attribute drops. Oher had another predictably bad 8 games, 12 sacks allowed. But he didn't lose any permanent ratings. The only one on the team that did was Jonathan Stewart, dropping a point in various categories as the weeks went on.
One note on the QB's...while I did say they aren't dropping AWR (at least young ones), they can still have others take a hit mid-season. One sim I did with Romo dropped him 4 DAC points after a 3 INT day.
