He is right on the brink of the top tier. Until they drafted Ben Roethlisberger they were never really a bonafide contender. It took him ten years to compete in a Super Bowl (the one where he got crushed by the Cowboys isn't something to brag about) although Tomlin was basically given a title by Cowher.

Go back and watch Super Bowl XXX again. The Steelers were dominating the Cowboys in the second half and were down by only 3 points with possession of the ball at their own 32-yard line with 4:15 remaining. If it wasn't for a ridiculous Neal O'Donnell interception returned to the Steelers 6 yard line (his second INT with no Steeler receiver in sight) the Steelers likely would have tied and may have won the game as they clearly had momentum on their side.
The fact that Cowher's teams made it to 5 AFC Championship games with the likes of O'Donnell, Kordell Stewart,
Mike Tomczak at QB speaks volumes about his coaching abilities.
I think Cowher is a better coach than at least 25 of the current coaches and possibly more.
