Al Davis created the modern-day NFL. There is no one person who has had a bigger impact on the league, PERIOD.
First to hire Black and Mexican coaches. First to hire a woman President. Helped create the Vertical Passing game with Sid Gillman. Conceptualized Bump and Run coverage. The list goes on and on. Al took care of his players and former players. The man took loyalty to the next level but was always prepared to fight for his principals. Scout, Coach, GM, Commissioner, and Owner. No one even comes close.
RIP AL DAVIS. LEGENDS NEVER DIE.
