I keep forgetting how the rules work with UFA. I'd be willing to bet he signs a two year deal and this is all moot but if he did sign a one year deal would he be eligible for UFA in 2020 or do you have to accrue 4 seasons so he's just a RFA? I think he has to accrue 4 seasons.. Still, I would expect whatever contract he signs to be very small and very short.
Personally I hope he can turn this into a financial positive because the CBA rules for RB's is grossly unjust and not only has it screwed RB's stuck on rookie wage scale but it's made those kind of RB's so attractive it hurts veteran RB pay. When they redo the CBA the RB's need a voice in that room, they need some kind of special consideration given to a position with a shorter shelf life.
