I have watched them both extensively.
Easley was a transcendental player. What I mean by that is that he was one of the first of his kind. Outstanding in coverage, great ball skills, but could move up and play like a linebacker. This is why he took the league by storm. He was unique. There was no other strong safety like him. Jack Tatum of Raiders fame could hit like a truck, but wasn't as good in coverage. Tatum more or less separated receivers from the ball and installed fear. Easley took the ball away and gave the offense field position. Since then we have seen the likes of Lott, Polamalu and various others. They were all patterned after the original Kenny Easley. He was the prototype.
I'm surprising myself by saying this, but I agree with Ronnie Lott. Before it is all said and done, Chancellor will be regarded as the best strong safety in league history. He is huge, athletic, quick, and very smart. He would be a dominant player in any era. If you were to ask me who I think the best single player on this Seahawk team is, I would say Kam Chancellor. If you were to change the identity of this team, if you wanted to severely cripple this team, you would remove Kam Chancellor.
There will be a few players from this team that will make the Hall of Fame. It would be a crime if Chancellor is not one of them.
