alot of fighters have this problem with their legacies. It is simply rare to have 3-5 great hw's around at the same time. I think Joe had a slightly better resume but there is no arguing that its fluffed up with alot of bums. Its hard to fault any fighter for retiring at 49-0 and staying that way, but Rock could have helped his legacy quite a bit by fighting Liston and Patterson when he still would have been in his mid 30's. I put Joe in my top three and Rock in my top ten all time HW's
