The Top 10 showdown weekend gets an early start Friday night.

No. 7 Stanford travels to Seattle to take on No. 10 Washington is a battle that will most likely decide the Pac 12 champion. For the Cardinal, a win would set up a solid chance for an undefeated season and maybe a trip to the College Football Playoff. For the Huskies, it's a chance to live up to the preseason hype.

Stanford-Washington all-time series

Friday's game will decide more than just the likely Pac 12 CFP candidate — it'll also give the winning team the upper hand and bragging rights in the all-time series. Currently, the series is tied 41-41-4, but Stanford has won seven of the last eight meetings between the teams after only beating Washington once between 1983-2003. The Huskies are also the Cardinal's second-oldest rivalry, making this a pretty heated matchup.

Numbers that matter

211.7

It's no surprise that Christian McCaffrey's stats are almost as good as his record-setting 2015. McCaffrey is second in the nation in all-purpose yards, averaging 211.7 per game. His average of 276 ypg last season will be hard to match, but through three games this season, he's already proved why he's a Heisman favorite. Just look at these numbers.

14

The Huskies love to pass. Quarterback Jake Browning is second in the nation in passing touchdowns (14), a majority of Washington's 17 total passing TDs. Browning's also very accurate throwing the ball with a 70.5 completion percentage (seventh in FBS). The Huskies won't shy away from the passing game against Stanford.

1-7

Stanford's track record on the road against ranked Washington teams is not that great. The Cardinal are just 1-7 when traveling to Seattle to take on a Top 25 Huskies team, and their lone win in Seattle against a ranked Washington team dates all the way back to 1975, a 17-6 win.

Social buzz

If there was any Pac 12 game to watch, Friday's game is it. With a not-super-late kickoff and the advantage of being the only Power 5 game on Friday night, there should be a lot of eyes on this Top 10 matchup in a conference most of the nation pays little attention to. Plus with a superstar like Christian McCaffrey and a team that's lived up to the preseason hype in Washington, this could be the best games of the weekend.

The big question

Will Washington spoil Stanford's party? For the first time ever, the Cardinal were picked to win the Pac 12 after not even being picked to win their division in 2012, 2013 and 2015 — their three championship seasons — and this season seemed to be their crowning moment with a shot at crashing the College Football Playoff. Now, Stanford has a huge obstacle in Washington to beat before those conversations can even begin.
