Buffalo Bills breakout star James Cook was cooperative to start training camp, participating in practice despite making it clear that he wants a new contract.

According to NFL Network insider Ian Rapoport, Cook has signed a four-year, $48 million contract with $30 million guaranteed.

If the Bills want out, they would have paid $22,035,000 of Cook’s contract and would incur a $8,040,000 dead-cap hit.
