I'm not a lawyer but I talked with a buddy last night who is. Even before this latest info, his comment to me was that there are certain rights you cannot sign away, no matter what the cba says or what a release form you sign says.
The burden of proof may be more difficult, but given the wording the suspension he felt some of the rights Zeke was denied are definitely cause for a winnable lawsuit. And winnable may not even affect the suspension, but could result in damages. He spouted a bunch of other stuff I can't remember which sounded bad for the NFL.
Any lawyers have comments?
