Miami Dolphins defensive coordinator Kevin Coyle needs to go.

I don't say that in a reactionary or angry way following Sunday's 41-14 loss to the Buffalo Bills. I have been critical of Coyle the past couple of years and wrote he needed to go after last season's December collapse by the defense.

Simply, the Dolphins defense has regressed steadily under Coyle for four years and last year's fall off the table was the worst of it...

...Until Sunday.

Forget that the Dolphins gave up touchdown drives the first two times Buffalo had the football. Forget that after the Dolphins made this a 34-14 game, the Bills, with their backup quarterback in the game, sliced through the Miami defense to make it 41-14 -- the final 41 yards on a Karlos Williams touchdown run.

The point is this is not going to get any better.

Kevin Coyle has turned Ndamukong Suh into an ordinary player.

The team has one sack all season and none in the last 11 1/2 quarters.

The Miami deep secondary is a mess, with Walt Aikens, semi-benched today, still getting enough playing time to provide no over-the-top help on a bomb to Chris Hogan for a touchdown.

There is no return from this, folks. yes, this defense might be better than this game at some point this season. But it will never be great.

Not under Kevin Coyle.

Oh, yes, who should take over?

DB coach Lou Anarumo has been a DC at the Merchant Marine Academy.

LB coach Mark Duffner has been a DC with the Cincinnati Bengals.

Jim Schwartz is unemployed. Bring in him tonight, if necessary.

Coyle must go.
