Quote Famous="Famous"I think you are comparing apples and oranges there to be honest. I wouldnt say that Rads, Hampson or Lydon were great full backs if we are talking about them in a world class sense.'"
Different styles of FB's but still equally as good in their own way.   
Radders wasn't a third pivot he was a world class support player who read the game very well.  Any sort of break and 9/10 times Radders is on your shoulder.   Add in deceptive pace, excellent under the bomb and rock hard defence and for me he was a world class FB.  
Not flashy but not everyone is.
