The committee ranked them third behind two one loss teams (Alabama, Oregon). How do you distinguish the rankings that make good predictions from those that do not? That rating is the basis for FPIs game-level and season-level projections. ESPN has updated its Football Power Index following the weekend's slate of games. Like most game predictions, FPI accounts for team strength, opponent strength and home-field advantage. Each quarterback's efficiency is determined based on past performance (using similar components as what we use to build up Total QBR), adjusted for an aging curve, and the players without any prior experience are set at replacement level. For ESPNs FPI projections, Ill look at them in two ways. ESPN cant even explain it. Over the past 10 years, a sample of 339 bowl games, the preseason Coaches poll predicted 59.9% of bowl game winners (163-109 with no prediction in 67 games with two unranked teams). What is the predictive accuracy of ESPN's FPI for game matchups? If a starting quarterback is out (or there is a chance he will be out), FPI accounts for how much better he is than his backup, and the difference between the two is accounted for in the game-level projection. Nine Big 12 teams were present in the top 15 of ESPN's FPI rankings for strength of schedule in the country. We support responsible gambling. Brian Fremeau looks back on Week 1 in college football and puts the opening games in their proper context.

Distance traveled: Like with altitude, long travel distances only impact a handful of teams, but in the most extreme cases (say, Seattle to Miami), hosting a team with a significant travel distance is worth about half a point per game, all else equal. Here are the projections for these games including the win projections from the preseason and their current projections. We know these use ESPN's recruiting rankings, but these are hit-or-miss at best, and truly non-predictive at worst. ESPNs preseason FPI projected that Arizona had 32.9% win probability.

Surprisingly, their accuracy was identical: 43 correct and 8 wrong or 84%. Over the last 10 seasons, the FPI favorite has won 75 percent of FBS-versus-FBS games, which is comparable to the Vegas closing line. Because of the level of detail in each simulation and the exhaustive process in building the model (see details on process here) we are confident that it will be remain of the most accurate systems out there for the upcoming season. This suggests one of the following things: The equation used is bad (recursion does not cause the converge to a value, or weights the input data incorrectly), the recursion is too extreme (recursively goes back to its raw input values), the data input is bad, or there is no knowable way to calculate a single uniform and meaningful value from the data points they useI think it is something like all of these combined. There may be a long way to go in the NFL season as were only now getting prepared to enter Week 14, but its never too early to start predicting which two teams will square off in the Super Bowl. In the preseason, FPI uses a number of predictive factors to project future team strength. It would be interesting to see how this ranking stacks up against other systems, like the Sagarin rankings, Bill Connelly's S&P rankings, or Ed Feng's The Power Rank. Gambling problem? Before the 2015 season, Connellys rankings depended on only success rate and points per play, which gives the term S&P. Fraction of games won.

Expected points added, or EPA, is a measure of success/failure that takes into account yards, turnovers, red zone efficiency and more to determine how many points each unit is contributing to the team's scoring margin. Seasonal effects: Over the last five seasons, offenses have contributed about 1.8 points per game to their net scoring margins in the first six weeks, but as the temperature (and offenses) cooled, the league-wide offensive EPA per game dropped to 1.0 points per game in the final six weeks of the season.
