Raiders are an AFC squad that plays the 49ers once every 4 years or so. It's always been more of a turf war between bay area residents than the teams themselves. 49ers and Cowboys historically have had games with huge ramifications usually resulting in championships. Guessing you're a younger fan.

Players in the digital age era are always commiserating after games now win or lose. Fans take rivalries much more serious than players.

49ers met the Cowboys 3 times in the playoffs during the 90's, not 4.
