OK....I was going to start a new thread about this but people don't tend to like new threads. This is the next best place for it.
I'm not posting this to bash Bo's defenses nor to roll in memories of the 90s. I want to know more about the differences.
The 90s defenses attacked QBs. We basically ran a 4-3 defense. I know at least in the bowl game against Florida, we faced formations with 3...4 and even 5 wide receivers. This would tend to lead Bo's defenses to be in nickel and dime sets which (as we have seen) leads to open running lanes because we have so many players focused on covering WRs.
So.....how did the 90s defenses get unbelievable pressure on the QB AND stop the run while still covering WRs? Bo's defenses are struggling to be able to do that.
I, very seldom, remember not having a 7 man front back then. So, if you had 5 wide, was each of them put in man coverage with no safety over the top? Even if you do that, that only leaves 6 in the box. (4 down linemen and 2 LBs.)
Is the main difference simply the safety?
If that's the case, I thought our DBs were the experience and strength of our defense coming into the season. Wouldn't it be a smart move to put them on an island and bring one more person into the box and make sure the QB knows the front 6-7 players very personally?
The biggest difference between the 90's and now it the style of offense that everyone runs. The spread type offense is designed to slow down the attacking style of the 90's type defense. In the 90's most teams ran a lot of Miami formations or Pro formation. Hardly any were sitting at 4 wide as their basic set formation. Even Spurriors fun and gun had a very conventional look to it most of the time.
The spread principles is all about making space for runners and receivers to run. They want one on one match ups. That is why you see lots of short passing, lots of zone read. A spread team loves to play an attacking defense, it creates more space to run.
BP big problem, and IMO is a philosophical one is that he doesn't want to give up the big pass play.
He loves bracket coverage. That creates gaps in the run defense. He needs to make a choice to bring more bodies into the box against a true spread team and give up a little of his pass coverage.
