I like Don Brown as a DC. He’s a proven commodity. He’s probably an upgrade over Baker for what that’s worth. The problem is, his numbers have been slowly trending downwards the last few years because offenses are adjusting to what he likes to do and he’s not adjusting what he likes to do. He’s going to play a **** ton of man and leave corners on islands. He’s going to bring pressure not just to rush the passer but against the run too. His defense will be better fundamentally than Baker’s (my high school DC was better with fundamentals) but there’s a reason he gets hammered by better offenses. You cannot just run the same coverages all game and not expect good teams to eventually beat you. Much like Baker runs the same front all game and good teams just attack the weaknesses in that front, good teams attack the coverages Brown runs all game.
Probably an upgrade over Baker but a risky choice because it could totally blow up in Miami’s face if they hire him and he doesn’t have new tricks up his sleeve.
