Rex Ryan has NOTHING to do with Marcel Dareus. He was drafted by Whaley/Nix prior to Rex even being here and Marcells problems were evident and was resigned by Doug Whaley anyways prior to Rex's first full season as head coach.
If any issue could be associated with Dareus it is with Doug Whaley, Jim Overdorf, Russ Brandon and Terry Pegula for putting these people in their respective positions to make these decisions.
