is a time to drop 8 and a time to send extras on blitzes. Last year when we actually did blitz the linebackers didn't really provide extra pressure. This year they are. That I think is the difference. You can blitz all you want but if you cant get pressure it puts you in more of a bind by not getting to the QB. They are doing much better with this this year.
I say they because in reality I have absolutely no clue who is calling the plays.
