Bills have most of the leverage given Cook is under contract through this season.. Nobody is going to make the Le'Veon Bell mistake again and give Cook big money after sitting out a year. Recouping the $5m lost not playing this year would be very difficult in his next contract. If they don't come to a deal Cook's best option is to ball out this year and hope to parlay it into a big contract next year. Beane knows this and it's just a staring game between him and his agent at this point.
