When he was a coach, Cowher was one of the best in the game. He won 149 regular season games in 15 seasons and led his team to a win in Super Bowl XL.
However, the fact that he has not coached in six years makes a big difference as teams attempt to target the veteran.
In the past few years, the NFL has become much more of an offensive league. Of the top 12 scoring offenses in the league this year, 10 of them are in the playoffs.
Conversely, twice as many teams fit in that range in 2006 but did not make the playoffs.
Various rule changes have made things easier for passers and the best teams are the ones that take advantage of it.
The problem is that this does not fit into the style that allowed Cowher to be successful.
Would you want Bill Cowher to coach your favorite team?
In 12 of his 15 seasons as a head coach, the Steelers were in the top five in the league in rushing attempts. In that time, his team never finished higher than ninth in passing attempts.
Cowher has never been known as an offensive guru, and his lack of expertise in this area will hurt his ability to succeed in this era of the NFL.
When Joe Gibbs returned to the Washington Redskins after a long gap, he was only able to lead the team to a 30-34 record in four seasons.
While the former Steelers coach has stayed around the sport as a television analyst, it might be too tough to expect him to quickly adapt to all of the league's changes.
Teams should let Cowher stay in his current position and leave the coaching to the newer crowd.
