Diazes scheme never worked, he just had a bunch of well developed studs handed off to him from Muschamp or Robinson's first stint under Mack, can't remember which....
So you're saying these coaches that have 3 years to earn a longterm gig here are going to come in and not try to develop a scheme for the players they have; but instead, try to fit square pegs in round holes? They only have 3 years to get all the round pegs they need to fit all the holes.... If they had just went back and watched the basic defense that Ash had last season that was improving toward the end of last season, and implemented that, they would be sitting on more wins right now. It doesn't mean they have to abandon the scheme they want to run. They can slowly include it and build on it as they recruit the players they need for it...But, why abandon something that was working for something you think you can make work when you have the right pieces? That's just called being locked in and stubborn...
I mean, I understand the fanbase, boosters, etc should be more patient and allow coaches to prove themselves, but that is just not reality...
