Harbaugh's and Dantonio's career records v. the point spread

Submitted by Dawkins on

With Michigan currently favored this weekend by 7 to 7.5 8 to 8.5 points, I decided to research how Harbaugh and Dantonio have fared against the spread during their careers and compile that info into the chart below. I didn’t include Harbaugh’s tenure at U. San Diego in the data because the database I used (www.teamrankings.com) doesn't have FCS data. I also didn’t include Dantonio’s time at U. Cincinnati because: (a) I’m lazy, and (b) who gives a shit about teams from Ohio? 

Caveat: Note that while comparisons like this are always apples to oranges (since you’re dealing with different opponents, different seasons, different rosters, etc.), this one is even more so since Harbaugh coached in the NFL for 4 years where the point spreads are generally much tighter than in college. So in the end, all of this might be pretty useless. Also, I’m not a statistician, so feel free to chime with your input on why this data does or does not matter.

2015 Season: In addition to the historical data below, I want to add that in 2015 MSU has a record of 0-6 against the spread and is -48 in expected v. actual point spreads (-8.0 avg), while Michigan is 4-2 against the spread and is +66.5 in expected v. actual points spreads (+11.0 avg).

I will now shut up and let you all analyze and draw conclusions from the data.

The metrics I consider in terms of "this is a good/bad coach" is straight-up wins as an underdog, and straight-up losses as a favorite.

In the long run, there are a lot of games where teams are 10+ point favorites or underdogs.  As long as it is not an upset, what's the difference if they covered?  It's still the expected result.

Anyway, that diatrabe out of the way ----- Michigan State is 11-8 straight-up in the 2010-2014 era as a underdog.  Say what you will about the particulars, but that is pretty good (anything over .500 is pretty good), and deserving of be-grudging respect.

Year-by-year details (all records are straight-up):

Stanford 2007: 3-7 as a dog, 1-1 as a favorite.

Stanford 2008: 3-6 as a dog, 2-1 as a favorite.

Stanford 2009: 4-3 as a dog, 5-2 as a favorite.

Stanford 2010: 0-1 as a dog, 12-0 as a favorite.

MSU 2007: 2-4 as a dog, 4-2 as a favorite.

MSU 2008: 0-4 as a dog, 9-0 as a favorite.

MSU 2009: 0-4 as a dog, 6-3 as a favorite.

MSU 2010: 2-2 as a dog, 9-0 as a favorite.

MSU 2011: 3-3 as a dog, 8-0 as a favorite.

MSU 2012: 2-1 as a dog, 5-4 as a favorite.

MSU 2013: 3-1 as a dog, 10-1 as a favorite.

MSU 2014: 1-1 as a dog, 10-1 as a favorite.

I was wondering about this.  A few weeks ago people were arguing that we wouldn't cover whatever our spread was because "Michigan has a history of not covering as a favorite."  I thought Harbaugh's record against the spread would be more meaningful than Michigan's as a program, since we no longer had Hoke, RichRod or Carr coaching us.

An interesting analysis, but does this say more about the coaches or about the oddsmakers?  A premise of making this comparison is the that point spread is gospel.    I'd be curious to see a study on the variance of point spreads to final outcomes across all college football, basketball and NFL games.

All the predictors and metrics are great and entertaining but there's one factor that matters. State and Mark Dantonio are playing a team they've never played before. I know that they've dominated Michigan in the last five years (even the same players) but they haven't seen this team. Everything is different now and if they come into this game underestimating that it will be a colossal mistake.

Oh my god the point spread, not their record against spread offences.

Took me like a full minute trying to decipher that chart before I realized.
