I'm kinda late to the party, but I'll go ahead and chime in anyway. Pittsburgh from a few years ago (with Polamalu, Hines Ward, etc.) is a pretty good comparison IMO ... but there's another team that I'm really thinking of that the Seahawks compare to -- (and I can't believe I'm saying this because I absolutely can't stand 'em) -- those Raiders teams of the 1970's. They had an Absolutely NASTY punishing defense (guys like Jack Tatum and George Atkinson) who would look to literally knock you out. Also the old classic Silver and Black attack was to run, run, run the ball -- pound you in to submission ... and then drop back with Kenny Stabler and connect on the long bomb to guys like Cliff Branch. To me, there are a lot of elements of those old Raiders teams in these current Seahawks. Remember, Pete Carroll played as a FS in college in the Bay Area and got his start coaching there as well. Carroll talked about that fact awhile back that his ideas about defensive backs and what a DB is supposed to look like ... came from watching those Raiders teams and guys like Tatum. So to me, there's a lot of those old Raiders (at least in philosophy) in the current Seahawks as well. I don't think that's a coincidence, as there's a part of me that believes Pete has tried to re-create that in some form or another.
