It's that time of the year again, when the seat begins to get quite warm under a few NFL head coaches. So as a handful of team executives prepare to replace their coaches, there's no better time to look back at how interim coaches have fared during the past five seasons.

Of the 12 mid-season changes since 2007, half of the new coaches have finished the season with a winning percentage of at least .500 (although that includes one coach, Jim Tomsula of the San Francisco 49ers, who went 1-0). Overall, interim coaches have gone 31-42 in that span.

At least three coaches have been replaced each year for the past four seasons, with the notable exception of 2009, when Dick Jauron was the only coach to get fired during the season.

Take note, Eagles fans.
