Having Porter wouldn't be a bad idea though he's a proven vet, plus Lebeau made him the player he is and was at his prime. I'm sure he'd take a pay cut to compete for another ring. He would be one hell of a back up if woodley, harrison, or timmons get injured, he's an OLB but can play the Inside as well.
I wouldn't say completely burned, the steelers had their chances at winning it, but thier secondary did get out played by GB's. The reason is because they love for Polamalu to come off the edge on a blitz, but they do need to keep him to defend the air a lot more. those CB's have to go though, taylor and gay didn't play well at all.
