Known widely as one of the most influential figures in NFL history, Davis also gained a reputation for fighting the establishment, first to move his team to LA and then for the rights to the LA market even after his team had relocated to the Bay Area.

Defying many an expectation, from his daily attire to his contributions in NFL oversight, the owner is mourned today across the sports world.

As ESPN mentioned in their writeup this morning, "'Al Davis's passion for football and his influence on the game were extraordinary,' commissioner Roger Goodell said. 'He defined the Raiders and contributed to pro football at every level. The respect he commanded was evident in the way that people listened carefully every time he spoke. He is a true legend of the game whose impact and legacy will forever be part of the NFL.'"
