The Buffalo Bills secured James Cook on a four‑year, $48 million extension with $30 million guaranteed on Wednesday, just eight days after the Los Angeles Rams locked in Kyren Williams on a three‑year, $33 million pact with $23 million guaranteed.

James Cook is back. The Bills running back signed a four-year contract extension worth up to $48 million. Cook's $30 million guaranteed is one of the highest figures in the league for running backs.

The Buffalo Bills and James Cook reportedly came to terms on a new four-year, $48 million deal, according to various reports, however, the deal is a bit lower than what the AFC star had been seeking throughout the offseason.
