Top 10 personal feuds in NFL history
4. Al Davis vs. Mike Shanahan
Some Broncos fans might find it hard to believe that two-time Super Bowl champion Mike Shanahan once worked for their hated rival: the Raiders. Back in 1988 the franchise was still based in Los Angeles rather than Oakland, and Shanahan was brought in from outside the organization to become the new head coach of the silver and black.
He wouldn’t even last two years on the job. Shanahan’s tenure was defined by frequent clashes with Raiders owner Al Davis, whose micromanaging style irked Shanahan to the point where their differences became irreconcilable. After two assistant coaches got into a heated argument on the sideline during a game, one of them went directly to Davis to complain about the other (who happened to be a Shanahan man). The Raiders owner resolved the squabble by promptly firing the Shanahan loyalist, which in turn incensed his head coach, who then fired several Davis hires.
Finally Davis used his trump card and fired Shanahan himself just four games into his second season, but Shanahan would get the last laugh by winning back-to-back titles with John Elway and the Broncos less than 10 years later.
