re: Who is the most savage player to ever put the uniform on for Bama?

Old School; John Hanna. You don't become possibly the best offensive lineman in history without a real mean-streak and land in the NFL top 25 players of all time. Joe Klecko called him the meanest player he ever saw play the game.

Modern; is has to be Ro. Just a full on enforcer. And just unhinged enough that you never knew exactly how far he was going to take things.
