Just think about this. The Steelers have had two coaches in 38 years. The Jets had that many coaches in a matter of 38 minutes in the past 6 years!
Shell will be out by tomorrow. That makes five head coach openings this year including Denny Green, Mora Jr. and Nick Saban. That's 12 head coach changes in the last two years. That's 37.5% of the league.
I could see Cowher coming back to the Steelers in a year or two... I just can't see him coaching another team
