Given all the talk before the Michigan – Michigan State game about “respect” as well as under and overrated teams, I found myself wondering which team in the Big Ten is typically the most overrated. I feel like MSU never meets their preseason expectations, but the same can usually be said about Michigan as well. Ohio State has been very solid within the conference, but obviously slips up once it goes up against the elite outside the Big 10. But which team is the most consistently overrated during the entire season?
I analyzed the point spreads for all Big 10 games for the past 10 years, 1999-2008. Team performance against the spread is well documented, but we don’t really care about ATS; hanging 50 points on Wofford when the spread is 40 does not an underrated team make. We want to break the lines down to victory or defeat, and see how the team performs in comparison.
W # of upsets against opposing team
L # of times being upset
TOT Total deviation from expected over total games
Stdev Standard deviation
PW Predicted win percentage
ATS Performance against the spread
Move over Mark Dantonio, there is a new Rodney Dangerfield in town. Yes, humble Northwestern earns the title of most misunderestimated in the Big 10. Meanwhile, Purdue is the most overrated team, although they have several teams not far behind, notably Michigan. I expected the Big 10 bottom-feeders to be the most underrated; when everyone expects you to lose every game, there is nowhere to go but up. Likewise, the big boys would be near the top. But Purdue has no excuse ... they have been given the modest task of winning 2/3 of their games, and they consistently blow it.
- Ohio State has the highest predicted win percentage @ 83%, as well as the lowest standard deviation. People expect them to win, and they oblige.
- Michigan State appears to perform as-expected @ -2.5%, but they have the highest standard deviation. Sparty wins a lot of games they have no right to win, and loses a lot of games for no reason, and basically acts very Sparty-like
- The third most underrated teams is Iowa. Given Michigan's overrated-ness, this does not bode well for this Saturday. Or it has no relevance, since Iowa is already favored ... I haven't decided.
- Purdue has only upset 6 teams in the past decade. Northwestern performed the same feat between 2005 and 2006.
- I expected the ratio of underrated teams to overrated teams to be closer. The Big Ten, not surprisingly, is not performing.
Thoughts? Is this a useful analysis of overrated-ness? Should this be expanded to additional seasons and teams? Spoiler-alert: I have already looked at Notre Dame, and they are not, repeat NOT the most overrated team in the universe.
