20 Richest Players In NFL History

10. Carson Palmer, QB — $174.1 million

Years Active: 2003-2017

Highest single-season earnings: $19.0 million (2014; includes $10 million signing bonus)

Once a promising young quarterback for the Bengals in the mid-2000s, Palmer suffered a near career-ending knee injury that would set him back some years.

He went on to have a resurgence late in his career with the Cardinals, and recorded his best season in 2015, at the age of 35.
