I know Tim Brown and Isaac Bruce had the longevity, but outside of this thread, when conversations about GOAT comes up, you don't hear those names. Honestly, you'll hear Randy or Terrell before you ever hear Tim or Issac. Fair or not, that's just how it goes.
As far as Warner...dude has an MVP and a ring...but he was playing football when Roethlisberger was in middle school and Roethlisberger already has more wins than him. And no way in hell would I put either of them in the HOF right now.
