Doug Williams, the greatest black QB of all time ( in my book),
and could have been the greatest of all time, was the lowest
paid QB in NFL, and 13 BACKUP QBs were payed higher than
him.

He turned the Buccaneers franchise around, and turned them into
true contenders. They were primed to compete for several SBs,
but the owner was candidly racist, and refused to pay Williams
on the same pay scale as other starting QBs.

The Buccaneers franchise fell into the cellar when he was basically
forced to leave, and they remained that way until the 2000s!
