Worsfold on 3AW gave a detailed explanation of the Judd injury - from memory he said it wasn't full OP because it only affected one side of his groin, whereas OP affects both sides.
Luke Ball has certainly been affected long term. I think Judd's a medical risk - walk away. Sometimes in life the price is too great and this is a classic case, clubs forming committees to deal with it, everybody prepared to go to the limit.
I have great trouble reconciling Carlton arrogantly holding on to pick one which they stole from us - I can't believe how everybody basically thinks what they did was ok. Let's never forget why they are where they are - they cheated big time.
