Even though Michigan State won with relative ease in its season opener against Western Michigan last Friday, it wasn't enough for the Spartans to get a lot of respect from the computers.

ESPN's Football Power Index ranks all 136 FBS teams, with the rankings updating after every single game all season long. Prior to the beginning of the season, FPI was already not very high on the Spartans, and the team's ranking dropped a little bit after the 23-6 win over Western Michigan.

How Far Michigan State Fell

With all the games in Week 1 now concluded, MSU dropped three spots in the FPI rankings. Michigan State was ranked 60th nationally before it took on the Broncos, and the Spartans ended up sliding three spots to 63rd.

The slide comes even though MSU's official power rating stayed the same: 1.3. That represents what FPI thinks MSU's expected margin of victory against an average FBS team would be on a neutral field.

Western Michigan also dropped in FPI's rankings. The Broncos ended up dropping more slots than the Spartans, falling five spots from 113rd to 118th.

Michigan State's ranking in the Big Ten stayed the same at 15th. Only one team in the conference that's on MSU's schedule ranks lower: UCLA.

What's also notable is that 11 of the Big Ten's 18 teams dropped in the FPI rankings, so the Spartans are certainly not alone. The conference's teams that experienced bigger slides than MSU are Indiana (down 5), Michigan (down 6), Rutgers (down 7), Minnesota (down 9), Northwestern (down 10) and UCLA (down 28).

Some Marks Still Went Up

Even though the Spartans dropped in the rankings, FPI's overall projections for the team still went up a little bit.

Michigan State's expected win total improved by +0.4, from 4.8 to 5.2.

The Spartans' odds at a bowl game also went up by 8.2%. Before Week 1, FPI had the odds for MSU to reach six wins at 30.6%. Now, it stands at 38.8%.
