It is really hard to say. I think Troy was a tad better. More consistent and less injured. But I think Sean Taylor was on his way to being the greatest of all time. I recently ran into a guy who plays rugby and also YT vids. He will watch players or hits suggested by fans. I said he should watch Ray and Ed as just some of the players he should evaluate. https://www.youtube.com/watch?v=U2Ggpdbra2A This is the vid I sent him.
