Week #4 National Rankings Update, Fremeau Efficiency Index, and Sagarin Predictor for Indiana

Submitted by Enjoy Life on
Technorati Tags: ,

I've added the Fremeau Efficiency Index. Also added the basic data for each category (score, rush yards, pass yards, etc.), the number of possessions, and the data per possession.

Synopsis: After 4 games, Michigan is currently ranked #11 in scoring offense and #64 in scoring defense. Based on these rankings, M has a 43% chance for a +5 WLM (9-4 or better) season and an 83% chance for a winning season. Note that if Defense rankings improve just slightly to the Top 60, the probability of a +5 WLM increases to 70%. Offense continues to trend better each week. Defense improved slightly. (See line chart below.)

Based on the FEI (Fremeau Efficiency Index), Michigan is predicted to win between 8.7 and 9.2 games (excluding bowl games but adjusted with +1 for M's one FCS opponent).

Based on the Fremeau Efficiency Index, M is favored by 18 points. Using the Sagarin Predictor, M is favored by 10.7 points in the Indiana game (Vegas Odds Opened at 10.5). Notice that the three Sagarin odds are very close to one another this week.

Overall this year, M is averaging 3.6 points per possession (PPP) and 49 YPP. The defense is giving up just 1.9 PPP and 33 YPP.

DETAILS: Here are the FEI numbers ( http://bcftoys.blogspot.com/search/label/Forecasts and http://www.footballoutsiders.com/stats/fei ).

GE = Game Efficiency (Basic data before SoS adjustment), MW = FBS Mean Wins for the Season, RMW = Remaining FBS Mean Wins

Note that FEI completely excludes all non-FBS data (the W-L record is only for FBS games, etc.). Therefore, you need to add 1 to the projected numbers to get the final predicted wins for M this year. The FEI is a drive based analysis considering each of the nearly 20,000 drives each year in college football. The data is filtered to eliminate garbage time (at the half or end of game) and is adjusted for opponent. A team is rewarded for playing well against good teams (win or lose) and is punished more severely for playing poorly against bad teams than it is rewarded for playing well against bad teams. I've included the GE basic data so you can see the impact of adjusting for opponent.  (See: http://www.footballoutsiders.com/fei-ratings/2010/fo-basics-our-college-stats )

Here are the Sagarin Ratings ( http://www.kiva.net/~jsagarin/sports/cfsend.htm ). I have added "Opps Rank" which is the total rankings (based on Sagarin Rating)of the opposition played divided by the number of teams played.

image

Sagarin uses two basic ratings: PREDICTOR (in which the score MARGIN is the only thing that matters) and ELO-CHESS (in which winning and losing only matters, the score margin is of no consequence). The overall rating is a synthesis of the two diametrical opposites, ELO-CHESS and PREDICTOR.

Per Sagarin: ELO-CHESS is “very politically correct. However, it is less accurate in its predictions for upcoming games than is PREDICTOR”.

Here is the U/M vs. Indiana National Statistical Rankings with the advantage for each category indicated (all categories within 10% are considered a "push"). Biggest differences are M rushing O (#2) versus I rushing D (#92) and conversely I passing O (#11) versus M passing D (#105).

Here is the line graph for Scoring Offense and Scoring Defense.

Here are the week by week National Statistical Rankings for Michigan (cumulative thru the week indicated):

image

I have included the major rankings for offense and defense but scoring rankings show the best correlation to winning and losing. Scoring rankings are based on PPG. Rushing, Passing, and Total rankings are based on YPG.

Here is the basic data for Michigan (each individual week followed by totals and then average per game). I've included Total Possessions for Offense & Defense along with the calculated data per possession. Number of possessions do not include running out the clock at the half or end of game. Offense Plays and Defense Plays are better indicators than Time of Possession.

image

Using Scoring Offense and Scoring Defense National Rankings for the past 5 years (FBS AQ teams only), this table shows the percentage of teams that finish the season with a +WLM and a +5 WLM. For example, teams that finished in the Top 40 in both offense and defense had a 100% chance to be +WLM and an 82% chance to be +5 WLM (9-4 or better).

image

Each year, of the 66 FBS AQ teams, 65% (43 teams) end up with a + WLM and 36% (24 teams) end up with a +5 WLM.

This is cool, but I don't think any numbers that Michigan has put up thus far are very dependable until after the MSU game.  If the current patterns hold similar through those first two Big Ten games, then I am on board with the ouput of such charts.

The numbers are solid.  

Not sure why you think Sparty is the relevant data point.  Sagarin has them with a schedule rank of 157 and there is a good chance they fall to Wisky on Saturday.  After a Sparty loss to us then we will hear - well Michigan hasn't proven anything yet they beat an overrated MSU team who's coach bla bla bla.....

I expect things to change in Big 10 play.  I look to Iowa as a test to see where we stand after playing an excellent defense.

Go ahead and believe!  What has been holding them back the past couple years?  Adjustment to new staff - check, QB with experience & time to learn the reads - check, ball security - check, ability to convert and move the chains - check.  This is a better team now.  The biggest weakness is experience on the D and that will only improve with more games played.  There is no reason they can't beat the teams they are supposed to this year and steal one or two more.

Only caveat I have on the rankings of Indiana's defense and offense - look at Indiana's strength of schedule (it's 200 out of all FBS and FCS teams, and there are only ~110 FBS teams) and how their opponents have performed against them. Their numbers are WAY overrated. UM's SOS is 77, I believe among the toughest SOS for Big Ten teams.

IU SHOULD have a highly ranked offense and defense, but their run defense is 92. This will be a replay of the UCONN game, with UM moving the ball up and down the field and eating up the clock. Add in that IUs offense is passing focused, and I think this UM offense and a couple of INTs and defensive stops means at least a 2 TD margin for UM in this game.

Notice that the FEI makes substantial adjustments for SoS. The column marked GE is the base data without any adjustment. M and IU are virtually equal -- ranked 10 & 11 based on GE. But, after the SoS adjustment M is ranked 21 and IU is ranked 81 for the FEI.

Thus, the spread based on FEI is 18 points. Much larger than most I have seen. We shall see how this pans out in less than 48 hours.

The one interesting thing that I keep seeing is the evidence that Michigan's numbers might look quite a bit better if and when we tighten up on special teams.  Particularly better origination points for our possessions, a few more points per possession by way of kicks.

Everybody knows that at some point, we're going to need some points out of our kicking game, and those of us who have seen all of the games so far know that our kickoffs have been margianal, our kickoff returns have been merely oaky, our punting unit has been barely-used but might be mistake-prone, and our punt returns have been plain awful. 

Special teams play ought not be subject to the kind of we-just-don't-the-requisite-number-of-bodies hopelessness that surrounds our defensive numbers.  Although I like the signs of improvement on defense, and I like the kind of determined dejection I saw with some of the defensive guys after the UMass game.  You'd have thought that game had been lost, judging from the guys I saw outside the Stadium.  I think their performance versus ND is a better indicator of what can be expected at IU.

This is from the footballoutsiders link...the more plays the more likely we make a big play and stop them. We just need to stop them a few times to come out on top...assuming the O produces - which is not a bad presumption.

Note that if Defense rankings improve just slightly to the Top 60, the probability of a +5 WLM increases to 70%

Currently, we're 43% to have +5WLM but moving up 4 spots in defense puts us at 70%????. In reality, it probably a sliding scale where say defenses ranked 60=70% 61-65=67% 66-70=64% ect....I don't know if theres a way to easily calculate this but we're probably closer to 65% to go +5WLM than the 43% you mention.

The only thing those charts show is that we are 4-0. Obviously if we maintain our current trend and score more points than our opponents we will win the game. Its really hard to put much stock into this for me because we UConn is 2-2, ND is looking like Michigan from 2008 at 1-3,  Bowling Green is also 1-3 and UMASS is still a FCS team.
