Rating the New Coaches: Buffalo
Buffalo won the MAC in 2008 under the guidance of Turner Gill. However, the Bulls were far from the best team in the MAC, so a decade long run at the top of the conference should not have been expected. After some anticipated regression in 2009 (though a 5-7 record at Buffalo should still be considered successful), Gill departed for Kansas and the Bulls hired Jeff Quinn as his replacement. Quinn had never been a head coach before save for two previous stints as interim head coach for bowl games at Central Michigan in 2006 and Cincinnati in 2009 (both times following the departure of Brian Kelly). Quinn was fired midway through his fifth season after a 3-4 start, and he finishes his Buffalo career with a middling 20-36 record. However, one could make the argument that he was relieved of his duties a bit prematurely. The table below lists Buffalo’s record, Yards per Play, Yards per Play Allowed, Yards per Play Net, Offensive Touchdowns (OTD), Touchdowns Allowed or Defensive Touchdowns (DTD), and Adjusted Pythagorean Record (APR). Keep in mind these numbers include conference games only and the ranking in parentheses is their standing against the rest of the MAC.
Khalil Mack. Sure enough, while the offense remained potent, the defense declined and the Bulls sputtered to a 3-4 MAC record (their game with Kent State was canceled due to hazardous weather). The Bulls fired Quinn after a 1-2 start in MAC play, and under his replacement, they split their remaining four games. So yes, the Bulls probably rushed in pulling the trigger on letting Quinn go (let’s not forget this team was 30-99 in the eleven seasons preceding Quinn's arrival since returning to FBS in 1999). However, despite their haste the Bulls may have actually traded up as they were able to nab Lance Leipold as his successor.
Who is Lance Leipold? Growing up with The Simpsons, when I hear the name Leipold, this is what I think of.
Alas, Lance is not that Leipold. This Leipold has been the head coach at Division III Wisconsin-Whitewater for eight seasons where he has compiled a ridiculous 109-6 record and won six DIII national titles. You might say Leipold had accomplished all he could at the DIII level. Now the Buffalo Bulls may have found a market inefficiency and hired themselves a great coach for the foreseeable future. Naw, who are we kidding? If Leipold has even a modicum of success at Buffalo, he will be snatched up by a Power 5 school in no time. What about the other point though? Are successful coaches from the lower divisions of college football (not intended to be a derogatory term) an undervalued resource? If they are, they may not be for much longer. From 2000-2012, seventeen FBS schools hired coaches away from lower-division programs (NAIA, Division III, Division II, or FCS); an average of roughly one and a half per year. These coaches achieved varying degrees of success and notoriety (from Jim Tressel to Mick Dennehy to Jim Harbaugh to Paul Wulff). This does not include successful lower-division coaches who took coordinator positions before moving up to FBS (like Hugh Freeze and Mark Hudspeth. In the past three offseasons nine such coaches have been hired by FBS programs, including six prior to the 2014 season.
How do these coaches who move up from the lower divisions perform once they get to the big stage of FBS? To answer that question, I ran a regression analysis using the seventeen coaches hired from 2000-2012. I used 2012 as the cutoff because that means each coach spent at least three seasons at his FBS school. The dependent variable in the regression analysis was the coach’s winning percentage at his FBS school. A few housekeeping notes on winning percentage: First, I used winning percentage because it was simple and easy to calculate. A better measure would probably be winning percentage above or below recent historical precedent. I am very lazy, so feel free to follow up using that. Second, I only included the first FBS stop the coach made. For example, Jerry Kill was hired as the coach of Northern Illinois prior to the 2008 season. He coached the Huskies for three seasons before taking the Minnesota job. His Minnesota career has nothing to do with whether he was a successful hire for Northern Illinois. The dependent variables I used to predict winning percentage were tenure as a lower-division coach (in years), winning percentage at the lower-division, and games above/below .500 at the lower-division. For tenure, I used consecutive years as a head coach at lower divisions even if it was at different schools. Thus Jerry Kill’s experience at Saginaw Valley State (DII), Emporia State (DII), and Southern Illinois (FCS) count as fourteen years even though he never spent more than seven years at any one school. I figured a coach with a longer tenure would be a better bet than one with a shorter tenure. I used winning percentage because duh, that is the object of the game. I used games above or below .500 as sort of a more advanced version of winning percentage to give more credit to coaches who produce good winning percentages over a longer time period. The complete list of the seventeen coaches included in this study can be found at the end of this post.

Andy Enfield. He was the head coach of Florida Gulf Coast, a school that took the nation by storm almost exactly two years ago. Dunk City became the first 15 seed to advance to the second weekend of the NCAA basketball tournament. After their run, Enfield became the coach of Southern California, a huge step up from Florida Gulf Coast. However, Enfield had only two seasons of head coaching experience under his belt and a middling 21-15 record in the Atlantic Sun. Since being hire by the Trojans, his charges have won a grand total of five conference games in nearly two seasons. Without only a short track record prior to being named the head coach at Southern Cal, it’s likely the powers that be in LA were Fooled by Randomness. Andy Enfield just happened to be standing around when some good sh*t happened. We should all be so lucky.
So back to Leipold. How does he measure up based on the three variables? Well, he spent eight years at Wisconsin Whitewater which is a solid run and makes him about average experience wise when compared to the lower-division hires examined in the study. His winning percentage of nearly 95% is tops by a healthy margin (Paul Johnson won 86% of his games in five seasons at Georgia Southern) and his games above .500 is twenty more than Brian Kelly accumulated in 13 seasons at Grand Valley State. If you are hiring a lower-division coach to lead your program, they don’t come much better than Lance Leipold. Add in the fact that Buffalo was probably a little better than their record indicated last year, and it’s easy to foresee a return to the postseason for the Bulls. As always, nothing guaranteed, but Buffalo appears to have made a great hire, even if he is likely at worst to double his number of career losses by the time he leaves upstate New York.
