Over the last 16 NFL seasons, PFF has graded every player on every play of every game to create the best source of NFL analysis available. There have been hundreds of great players over that time, but the biggest football database on the planet allows us to focus on the very best to ever do it.
To celebrate the modern-day legends of the game, PFF has created exclusive NFTs to award to these players, the PFF immortals, who will go down as some of the greatest players in NFL history.
A first-round draft pick from 2014, Aaron Donald is going into his ninth NFL season after winning a Super Bowl with the Los Angeles Rams in 2021. He has never earned a PFF grade below 90.0 over a full season and has been the league’s best pass-rusher — at any position — since entering the NFL.
