I said in a previous thread that Fury didn't have power to go to the top , and this fight proved that ,his technique will improve , but he doesn't punch hard at all.
As for the fight well it was hard to make a case for Fury as a winner. But the fight was a good one , and both men showed heart , a rematch is the only fair way to sort it out.
As for Fury thinking he is World class , then that's as ridiculous as Floyd Mayweather SR. thinking he looked good with the predator haircut !
