Good list! I'd recommend you add Dexter Coakley and Sean Lee. Coakley had no weakness - the guy was great against the pass and run as a WLB. I know Lee had injury issues, but he was a HOF talent and played that way when healthy (not to mention being one of the best leaders we've ever had). I'd take either over Norton (who played both MLB and WLB for Jimmie Johnson, but had a much shorter prime for us thanks to his FA departure).
