How many coaches does it take to screw in a lightbulb?
Insert your own punchline here. Whatever it is, the continuation of that joke goes into how many coaches are necessary to manage an NFL roster. The Steelers say it's 15, which is the least amount of coaches employed by any team in the NFL. The Philadelphia Eagles and Seattle Seahawks say it's 24.
Less doesn't mean more very often in football, but over-coaching is a concern at any level. Fewer coaches have fared well for the Steelers, having the fourth-best win percentage in the NFL since 2008. The Patriots, who have the most regular season wins since 2008, and Falcons, who have the second-most, both have 17 coaches - second-lowest in the league.
On one hand, fewer coaches means fewer people the head coach must directly manage. That helps ensure a clear, smooth message is passed from coaches to assistants to players. On the other, more coaches means more eyes watching the team, and any input could be considered valuable, with the right culture.
Clearly, there's no hard-and-true answer, but it is interesting the Steelers would have two fewer coaches than the second-least amount in the league.
