See my previous post. The talent changed, thus the system had to change.
You are cherry picking one bad season from Tomlin to paint him as a bad coach. He may or may not be, but you are chumping to conclusions based on one bad season.
This reminds me of 2003. Steelers went 11-4-1 in 2002 and completely fell apart in 2003. It was the secondary and the OL that was the problem then and now. Enter Polamalu in 2004 and a healthy Marvel Smith and boom…6-10 turns into 15-1.
Cowher is a Big Ben shoe-string tackle away from being Marty Schottenheimer. Not that that’s a bad thing. He did a great job with the Stillers, but he had his down seasons too.
Why not bash Colbert? He picked Timmons over Leon Hall in 2007 and then Mendenhall over Chris Johnson in 2008. Those two changes might have helped our running game and pass defense, eh?
