He is not the same CEO style coach he was at UF.
Im not convinced this is true, and I'd say there's a fair chance that he IS the same style and that is at least part of the reason it isnt working.
He was a master manipulator of kids in highschool/college. He was relentless with kids he was recruiting and promised them the world. Then, once on campus he was very different with them but used a lot of psychological tactics to get them motivated to perform. Because they were in college and he held their college and pro prospects in his hands, kids played hard for him despite not liking him, and because they were very talented, we saw a lot of wins. But none of that really translates in the pros.
He cant step on the field and be better physically then most every team due to his recruiting chops. There is no crootin; thats a huge advantage he had that is eliminated. On top of that, the psychological games and ability to get players to perform out of fear is basically out as well. These guys are adults, all with contracts, and most getting paid more than he is. In college you address your HC as Coach or Coach XXX, or Sir. In the pros you call him Bob, or Jim, etc. It's just different, there's no power you really hold over them and without his crootin prowess to be leveraged for his advantage, hes just a meh guy. There are some exceptions to the psychological gamesmanship in the NFL - belicheck being a prime example, but it isnt the norm and usually doesnt work out. It didnt for belicheck until a guy named Tom came along. So was it really that, or something else?
