I was never that impressed with Clyde Christensen at Indianapolis. I'd put him somewhere in the middle of the pack, but he obviously benefits by having Adam Gase in Miami. Christensen's best attribute seems to be his work in the passing game.
Darren Rizzi is probably in the top half of the league in terms of special teams. He is described as driven, much like Gase.
The question mark is Matt Burke as a new coordinator taking over for Vance Joseph. I'm hopeful that he's smart enough to make some changes from last years' scheme, especially in terms of the much discussed Wide 9 format.
Miami's defense was at its best last year in crucial spots, a tribute to Joseph who honestly didn't have much to work with at linebacker and a lot of new faces in the secondary.
