A professor will provide his view of turnover among head coaches in the National Football League on the next edition of the “MTSU On the Record” radio program.

Host Gina Logue’s interview with Dr. Michael Roach, an assistant professor in the Department of Economics and Finance, will air from 8 to 8:30 a.m. Sunday, May 31, on WMOT-FM (89.5 and www.wmot.org ).

After analyzing all NFL teams between 1995 and 2012, Roach concluded that, on average, teams fare even worse in the win column after changing head coaches.

Roach discovered that firing a head coach reduces the next season’s win total by eight-tenths of a win, the difference between the number of points scored by the team and the number of points scored against it by 27 points and the likelihood of making the playoffs by 12 percent.

“If you’re an organization, and you think that a change of coaching is going to change your on-field fortunes overnight, I think it’s useful to understand that that’s, on average, not the case,” Roach said.

Roach, who teaches sports economics at MTSU, published his research in the academic journal “Applied Economics Letters.”
