You can crucify me in the comments for it, but I don't really care anymore that LeBeau practically invented the modern 3-4, the zone blitz or anything else he's been given credit for over the years.
He can't coach anymore. It's becoming more and more evident that this team needs a change on that side of the ball.
LeBeau's reputation as a defensive genius is the only thing stopping him from looking for a new job.
Let me break down the defensive issues for you as best I can.
The first problem is that the front seven generates little or no consistent pressure on opposing quarterbacks. I don't buy the James Harrison injury as the reason.
I don't even buy the age argument. This unit features Brett Keisel, LaMarr Woodley, Lawrence Timmons and Ziggy Hood. That's plenty and is more than some teams have for pass rushing.
The problem isn't the talent. The problem is that LeBeau seems ideologically opposed to doing more than sending his outside linebackers and corners for blitzes. Lawrence Timmons might as well be playing safety or corner. Trying to get more out of the defensive ends or the nose tackle is lost on Pittsburgh.
The secondary is a mess too. That's partly because there's no talent at corner behind Ike Taylor. A bigger problem is that LeBeau is way too dependent on Troy Polamalu to make everything work on defense.
That means that most of the time Pittsburgh is playing with three defensive backs. Ryan Clark can't do everything.
The Steelers really need to spend the offseason pondering a switch to the 4-3 defense and a huge change at coordinator. Getting LeBeau to quietly retire gracefully would be the best way to handle this.
A bonus would be if he retired during the bye week and handed things over to Keith Butler, who's been waiting forever to get that job. That way, we might get to see if he can do something before spending another season trying to find out.
