Norcaleagles:
First of all, the game against San Diego was during the regular season, not a playoff game.
Secondly, you apparently have not watched many Raiders games or you would feel differently. We were screwed out of a repeat Super Bowl performance while playing against Denver in 1977, when Rob Lytle fumbled the ball as soon as he hit our line. We recovered and ran it back for what would have been the winning TD. The only thing is that the refs never saw him fumble and ruled him down. Add in the Immaculate Deception, the Tuck Bowl and the Tony Siragusa body slam of Rich Gannon that was even flagged although it broke Gannon’s collarbone and Raider fans begin to believe that the NFL refs are against them. Add in a few more strange calls over the years, including the game against San Diego in which a Charger receiver catches the ball, falls to the ground and isn’t touched but gets up and spins the ball. Oakland recovers but it is ruled an illegal forward pass. Or the game against Seattle when our safety intercepted the ball at the 3 yard line but slides into the endzone and is touched by a Seattle player. Not only isn’t the play ruled a touchback, but Seattle gets two points for a safety and the Raiders have to punt the ball back to Seattle
