Ok so let's hear your top 5 worst legitimate heavyweight champions. Let's say the fighter had to at least beat a recognized belt holder. So I don't want to see any Charles Martins.
Hasim knocked out Lewis which is not easy, Shannon isn't a bad pick,,, Ing, Leo and Fury all beat the top guy of the time at least. For me Wilder has to be there, mind you he could change that with one solid defence of his title against one of the top guys. Providing he wins.
Braddock probably should be on my list, maybe take Rahman out. Tommy Burns could get a shout but I'd put him ahead of the other guys I've named.
