Aaron Donald
A few days before the start of the 2018 NFL season, Aaron Donald signed a new six-year contract with the Los Angeles Rams, worth 135 million dollars, with 87 million guaranteed and a 40 million dollar signing bonus. This made him the highest-paid defensive player in NFL history, but less than 24 hours later, Khalil Mack reclaimed that record by signing a 141 million dollar contract with the Chicago Bears.
