I understand the term well. I just haven't seen 8 men in the box with the exception of the Giants game. And even if the safeties are playing slightly closer than they normally would, they are not "selling out, to stop the run."
The defenses we have faced have mostly double-covered our WR's with a safety and CB, and allowed them to read-and-react to any running plays. Teams are NOT blitzing us or sending extra men to stop the run. They are playing disciplined coverage schemes, overpowering our offensive line with a four or five-man rush, and allowing the linebackers react to the ball.
If that means an obvious passing situation (and almost all of our play-calls have been obvious) It means 6-7 guys are back in coverage, and they are STILL getting pressure on fiedler.
I don't mind the term 8 men in the box when it is being used properly. But people are using it as an excuse for the O-line, and trying to make it sound like they are facing more men than they can block. Which in turn would mean someone, somewhere should be uncovered or at the very least one-on-one. But that is not the case. The O-line is often being beaten one-on-one, or even very often with MORE O-lineman than rushers.
