if it wasn't for Ed Reed he would have been the best of his era. but Ed Reed balled out at the SS (did it better than troy) and FS!
I'd take him over Reed, barely. Reed was the best coverage safety, but I'd take Polamalu because of his run support and disruptive ability at the line.
Whenever I think of Polamalu I always think of this one play, I can't even remember who they were playing. It was a perfectly executed screen where a runner has a convoy of blockers in front of him in an open field and it looks like it's gonna be a 25 yard gain. Polamalu flew in from out of nowhere and somehow split/shrugged off 3 blockers and blew the runner up behind the line.
Dude was like Wolverine playing football.
