I dont know how someone could say Miami D is better right now. We had 1 loss on defense in Pat Williams. Many people (besides bills fan) feel that Edwards can more than fill the void, he is just as big but much much quicker than Pat and saw plenty of playing time last year and provides a pash rush that was is nonexistent in Pat Williams game. (4 sacks I believe last year). He will only benefit playing along side Sam.
McGee will have a full year of corner under his belt, he struggled early but improved vastly over the end stretch. Milloy is healthy again missing him the first 4 games really hurt and Vincent now has a full offseason to make his transition to FS even easier.
We dont really have a question mark on our defense while your secondary is a big question mark. Plus saying that the Jets are the worst D in the AFC East is far from true, and putting Saban up there with the likes of B.B. is the most homerific thing I have ever heard, he is a ROOKIE HC for christ sakes.
