After a months-long contract dispute, the Buffalo Bills and James Cook reached an agreement on a four-year contract extension worth $48 million with $30 million in guaranteed money. In terms of total value, Cook is the highest-paid running back in the league.

After securing a big payday and a four-year deal to stay with the Buffalo Bills, running back James Cook couldn't hide his satisfaction.

An emotional James Cook put pen to paper Wednesday, signing a contract extension through the 2029 season just one day after the two-time Pro Bowl running back rejoined his Buffalo Bills teammates in the backfield.
