I have done a poo ton of research on this cap thing and have been advocating keeping for a long time. Nobody has presented a logical reason(including cap implications) to cut him now. Appearently Gettleman agrees that cutting him now makes no sense what so ever but yet CRA continues his blind hate for D-WIll.
It has nothing to do with Williams if you actually listen to the argument.
It has to do with a limited amount of rushing attempts available....and the money better suited to go toward a player that plays every down.
