Sir Bob Jones weighs in on Joseph Parker's odds

New Zealand boxer Joseph Parker says it would just take one clean hit to get his opponent Anthony Joshua out of the ring. In three days the heavyweights will face off in front of 80,000 people in Cardiff. Anthony Joshua's trainer Rob McCracken says it doesn't matter how well Parker's preparation has gone, he won't have what it takes to stop the 2012 Olympic gold medallist.
