This may seem like a strange post, but I can't seem to recall a defense that extensively uses line slants and is also dominant. A proxy would be a team like Pittsburgh (Steelers not Panthers) that blitzes more frequently. Slanting is a good tool to mix up reads or disrupt offensive tendencies, but a big gamble when you are not allowed to read and have committed before the play develops.
The reason for the question is that I am not sure we can play a good line straight up. Yes, we make these halftime adjustments which seem to be more slant and blitz packages where we are going for broke. Granted that has worked the last three games, but then the entire first halves have left a lot to be desired. We could blitz more, but IMO it seems we are most effective when we slant more which takes advantage of our speed and deemphasizes our smaller size.
However, slanting is a pre-snap gamble and I don't know if you can continually use it over an entire game since you will be running yourself out of plays (better than getting run over I guess). I just don't see an alternative at this point considering the rushing yardage we are giving up. Granted, better LB play would help the problem and we have pretty much given up hope for any quick turn around based on some recent posts. You just can't cover up dudes getting pushed around (BG not included).
I would like any of the defensive gurus on the board to weigh in.
