Depends How IMO.. Bernard outboxed Pavlik for 12 FULL Rounds ! I Think Roy has to either stop Calzaghe or win by UD to top that..
Jones beating Calzaghe would be a far bigger upset at this point in his career, so I'll go with that. That said, for Hopkins to beat a P4P 26 year old at the age of 43 is the greater actual achievement - it's just that it wasn't that unexpected.
