The other teams do have pro players as well. They have O-Lineman that are at an NFL level. I just think that's a bit of a stretch to assume that teams don't do more then just add other blockers towards AD to handle the RAMS D. Look at last year....Troy, Floyd both had multiple sack games, they got sacks and pressures from various players.
IMO it's hard to get pressures and sacks in the league even with a All World guy like AD it's not just "hey he's getting the attention" type thing....teams do more then just put pads on AD to avoid those sacks and pressures...quicken their throws, move the pocket...hide directions of the ball..etc.
Everyone here would love improvement for sure, but they are coming off a #1 rank year, and that was with several "Considered" pass rushers on the mend for a good part of that whole year.
