Adjusted Win Percentage for Conference USA Coaches

                                  


I've often felt that winning percentage is not a great look at how good coaches actually perform as it does not factor in a multitude of items including environment, player talent and competition. As a result I devised a formula to try and tackle some of that problem and give a more accurate portrayal of what part of the wins and losses the head coach was responsible for. 

This metric, the adjusted win percentage for FBS coaches, tries to take into account at least the players that each coach is responsible for. For example when a new head coach wins in their very first year the credit only lies somewhat with them. Many of the players they are winning with were recruited by the previous staff. Often these coaches go on to not be successful in the long term. The best examples I can think of are Ed Orgeron at LSU or Gene Chizik at Auburn. Both should be noted actually had their best year a few years in, but neither lasted after a prolonged time. On the flip side new coaches often lose heavily in their first year because it takes time to recruit and install new systems and to get a full buy-in from players. Think Sabin's first year at Alabama or Bobby Petrino's first at Arkansas.

The basic thrust of the formula is this, the longer a coach has coached a team the more accountable he is for their wins and losses. The transfer portal has changed some of this in that the formula now holds coaches more accountable sooner. Gone are the days when you had four years to show some results.

Special notes, these statistics are based on fbs wins and losses only. The time period for the coaches is endless so all the coaches years are included, but it is only an evaluation of current coaches not coaches from the past. 

With all that being said this is the third piece in this series. This time we look at Conference USA. There is a clear and away winner in this category and it's not particularly close. It's Jamey Chadwell at Liberty. Chadwell created a fringe powerhouse at Coastal Carolina and his first year at Liberty was a success as well. The adjusted winning percentage metric has Chadwell at a 75% clip which ultimately ranks him as one of the best coaches in the country. He's a full 12.5 percentage points ahead of 2nd place coach Rich Rodriguez. Note: Brian Bohannon has not coached as an FBS head coach at this point which is why his stats are nil for this metric.

Adjusted Win Percentage for MAC Coaches



I've often felt that winning percentage is not a great look at how good coaches actually are as it does not factor in a multitude of issues including environment, player talent, competition.

The transfer portal has changed some of this in that the formula now holds coaches more accountable sooner. Gone are the days when you had four years to show some results. 

With all that being said this is the second in this series. This week we look at the MAC conference. Miami (OH) finished on top of the MAC last year, but it is Ohio coach Tim Albin who has the best adjusted win percentage. Albin has an adjusted win percentage of 65.2%. The Bobcats went 10-3 last year and have fared well under him in three years. Albin's worst year there was his first which of course the adjusted win percentage devalues.

Adjusted Win Percentage For FBS Independent Coaches




Over the next coming weeks before I break out predictions and rankings for each FBS conference I wanted to introduce a new analytic. I've often felt that winning percentage is not a great look at how good coaches actually are as it does not factor in a multitude of issues including environment, player talent, competition. As a result I devised a formula to try and tackle some of that problem and give a more accurate portrayal of what part of the wins and losses the head coach was responsible for.

For example when a new head coach wins in their very first year the credit only lies somewhat with them. Many of the players they are winning with were recruited by the previous staff. Often these coaches go on to not be successful in the long term. The best examples I can think of are Ed Orgeron at LSU or Gene Chizik at Auburn.

The transfer portal has changed some of this in that the formula now holds coaches more accountable sooner. Gone are the days when you had four years to show some results. 

With all that being said I will be laying out each conference with teams and coach and what their adjusted win percentage is in the next week or so.

First up is the FBS Independents. There are only three unaffiliated teams this season in the FBS and for sure they're led by Notre Dame and fairly new head coach Marcus Freeman. I have to admit I had my doubts about Freeman, but he has prevailed and many see the Irish as a possible national title contender this season. Interestingly all three coaches in this grouping are going into their third year, but at this point only one has had success.

Best Coaching Jobs in 2023 (Point Differential Above Expected)

7/22/24 Correction: There was an error on the formula page when I first calculated it. I’ve fixed it and it changed the results slightly. Who did the best coaching jobs in 2023? This measurement might give us an idea. The was the Aggregate metric works we can come up with a rating of points above expected. This statistic is measuring how well a team actually did as compared to what they were supposed to do before the season.  In this case each measurement shows the difference in point differential for each team than what was expected. Do not expect to see Michigan on this list. The Wolverines were the Aggregates preseason #3 and they finished #1 and yet they finished  with a -0.5 points worse than expected rating, meaning that their differential was just 0.5 points off what the Aggregate expected. That made them 42nd on the list.


#1 Jedd Fisch-Arizona


Point Differential Above Expected: +16.9

Record in '22: 5-7 (3-6)

Record in '23: 10-3 (7-2)

Fisch finally achieved success in his 3rd year in Tuscon. The Wildcats went from the back of the pack in the Pac 12 to the top in what ended up being the Aggregates 2nd best rated conference. Fisch took his success and headed to Washington for the 2024 season.


#2 G.J. Kinne-Texas State


Point Differential Above Expected: +15.4

Record in '22: 4-8 (2-6)

Record in '23: 8-5 (4-4)

Kinne came from FCS school Incarnate Word and had success in his very first season. Some of the highlights include beating Baylor and S#outh Alabama in a bowl game. Don't let the 4-4 Sunbelt record fool you as the Aggregate had the Sunbelt as the best group of five conference. Kinne returned to the Bobcats for the 2024 season.


#3  Rich Rodriguez-Jacksonville State


Point Differential Above Expected: +15.3

Record in '22: 9-2 (5-0) (All games against FCS opponents)

Record in '23: 9-4 (6-2)

Rodriguez helped guide Jacksonville State through their transition to the FBS and the Gamecocks had no issues. The Gamecocks won their first bowl game in their first year in the FBS. No team has ever done that before. Rodriguez returned to Jacksonville State for the 2024 season.


#4 Jamey Chadwell-Liberty


Point Differential Above Expected: +14.2

Record in '22: 8-5 

Record in '23: 13-1 (8-0)

Chadwell moved took the reins from Hugh Freeze and the Flames have soared. Liberty won Conference USA last year their first year in the conference. Liberty had one of the easiest schedules in the nation, but did even better than expected against those opponents. Chadwell returned to the Flames for the 2024 season.


#5 Barry Odom-UNLV


Point Differential Above Expected: +14.0

Record in '22: 5-7 (3-5)

Record in '23: 9-5 (6-3)

Odom changed the perspective in UNLV and made them a contender in his very first year. The Rebels played in the Mountain West Championship and went to a bowl game for the first time since 2013. Odom returned to UNLV for the 2024 season.


#6 Deion Sanders-Colorado +11.4

#7 Brent Brennan-San Jose State (Now at Arizona) +10.7

#8 Alex Golesh-USF +10.5

#9 Ricky Rahne-Old Dominion +9.7

#10 Scott Loeffler-Bowling Green +9.3
