Our CB's were so bad that Steele couldn't even run his base coverage because they were getting cooked.
For those who don't know...
Steele is a big Cover-3 "Match" guy...with press alignment on the outside. He literally said in one of his first clinics at Miami..."We are a press team. We are going to disrupt routes."
Well when the defensive staff got to Miami, our Corners didn't even know how to properly play press. (thanks Manny)
The staff spent a ton of energy reteaching them how to properly perform the fundamentals of coverage. This is part of implementing a new scheme. Coaches do it across the country.
Well fast forward to 4/5 games through the season (?), our CB's were getting cooked on deep vertical routes. It was evident at that point that we couldn't run our base scheme. I literally watched them change their scheme to a more of a loose zone Cover-2 shell to try and salvage some defensive success/momentum.
Some people might say "well you shouldn't be running that scheme with those players". But that's not how it works. Finding out what your players can and can't do, takes a little longer than people think. It takes at least a few games of live action versus an opponent. Every week you try to "coach it up" as best as you can until it's blatantly evident that they can't perform the duties required. If you change the scheme too quickly, instead of coaching up the players, you essentially show the players that you don't believe in them.
Coaches that have been doing this for 30 years have a system that they believe in. With that system, you need certain type of players. You are not going to change the system that you've been running for 30 years to fit around a lack of talent. Not at a level of football where you can actually cherry pick what you need. This isn't high school.
Steele didn't have what he needed at CB or LB. (particularly CB)
