A championship series like the Stanley Cup Final brings the teams in a city together even more than they already are because every team and fan in that city (for the most part) rallies around that team that can win a title.

Although the Oakland Raiders haven't moved to Vegas yet, they're still showing support for the Golden Knights and they did so ahead of Game 1 by taking out a full page ad in Monday's Las Vegas Review-Journal.

As per ESPN's Arash Markazi, Raiders owner Mark Davis will be in attendance for Game 1 Monday night to cheer the Golden Knights on.

The Golden Knights aren't the only team that the Raiders have taken out a full page ad to wish luck, either.  Ahead of the Las Vegas Aces' first WNBA home game, they took out an ad and Davis attended the game, too.

The Raiders are still two years away from becoming Las Vegas' football team, but they're already starting to build a relationship with the other pro teams in the city and we're sure if they make the playoffs this season, the favour will be returned.
