Week 1 should be awesome.There are a number of high-profile games on tap right off the bat. Among them are Michigan-Notre Dame, Alabama-Louisville, LSU-Miami and Virginia Tech-Florida State.However, according to ESPN, none of those four are as crucial to the College Football Playoff race as Auburn-Washington.Today, the Worldwide Leader put out a Week 1 primer based on its Football Power Index (FPI). The computer says the Auburn-Washington matchup is the most important for the CFP.Here’s why:There’s plenty to play for in college football — bowls, conferences, rivalries — but when we strip it down, this is what matters the most, right? A ticket to the playoff and a shot at a championship. Neither team in this game reached the playoff last season, but based on our FPI projections both are immediate contenders to get there this season — especially with a win in this neutral-site game. By our adjusted leverage metric — which considers each team’s chance of earning a top-four strength of record depending on the result of their game and how likely that result is — no game in Week 1 matters more to the playoff race than this one. In fact, it’s the third-most important game for the playoff race in the entire season and it’s a coin flip — FPI gives each team a 50 percent shot to win.If Washington wins the game, it would have a 51 percent chance to have a top-four SOR (our playoff proxy), while Auburn would have a 35 percent chance with a win.Now, we haven’t crunched the numbers like ESPN has, but Michigan-Notre Dame is also a strong contender for most important Week 1 game. Notre Dame could really use a resume booster right off the bat, particularly since the Irish don’t belong to a conference.Michigan, meanwhile, could lose to Notre Dame and still make the playoff. But it would have to run the table after Week 1 and that’s really tough when you have to play at Michigan State and Ohio State and also host Penn State.Auburn and Washington will face off at Mercedes-Benz Stadium in Atlanta on Sept. 1.
