In general, how have the defensive line scheme changed from Fangio? Have the nose tackles and defensive ends been playing two gaps or one gap? I know the ILBs are as good as prior years, but how is the DL doing in run defense so far this season?
They're playing 2 gap, Williams is doing a pretty darn good job in the run game, just not getting any sort of interior rush. I would Dorsey is doing well, and Dial is lagging behind the two. What I don't think he's doing a tremendous job of, is keeping his LB's clean. Here's an example from last game. 8:53 1st QTR
Balt is going to run a stretch right, off tackle run. Should look very familiar, as we run this a lot as well.
Dial was just a step slow off the snap, he should be firing out, at minimum, to the T's inside shoulder. Ideally, you'd like to see him reach the guard - that's what J. Smith was able to do. That way, you'll eat up two blockers. I remember hearing Warren Sapp talk about the need to do that on stretch plays, the T is going to block that 4 or 5 tech, so you, as the DT, have to reach for that G to take on a double team. Instead, Dial takes the T's outside shoulder.
You see him take on the T's outside shoulder, this free's up the G to move to the 2nd level on Bow. Dorsey does a good job of eating up two blockers on the play side and Williams does a good job of standing his man up and watching for the ball.
Dial then lets the T go - for some reason, that's not his job. He needs to keep his LB's clean, that's his primary job. The guard tries to cut block Bow and Bow does a great job of avoiding the cut block. The RG peels off Dorsey and tries to move to the 2nd level, but he was delayed in doing so, which allowed Wilhoite to fill the gap. Then, Dorsey has still done such a good job, the FB has to help the RT. So, at this point in the play, Dorsey has occupied 3 blockers at one time or another.
Forsett presses the hole and now the RT is able to peel back on Bow. Dial should've kept his man engaged, and then Forsett wouldn't have had anywhere to go. You see Williams flash some color inside, then watch for the ball carrier to make his cut.
Because the LT is free to peel back on Bow, it creates a cutback lane. Williams did a great job of standing his man up and watching for the ball carrier, so he's swung back around to where the runner is coming.
Bow still, somehow, gets past his 2nd blocker and he and Williams make the tackle. However, it's still a 7 yard gain. 7 yard gains allowed, esp. against the Seahawks - who run the same run scheme, will get you killed. This is a 7 yard gain off RT, but, it's really on Dial.
