Wards just entered the scene as a real champion. He has plenty of challenges ahead of him but that is one bold prediction. I wouldn't back it but I feel like he's not going to lose for a long time.
RJJ did it with his athletisicm with youth and speed and timing on his side but when he got older, his speed and timing diminished and that split of a sec on the reflex that could have avoided the punch now is KOing him. Bottom line, RJJ relied on speed and athletisicm with youth but he never had good boxing fundamentals and defense and B-Hop even said it himself. Ward is a different fighter, he is smarter, better fundamentals and better defense and it gets better when he gets older like B-Hop Now are you understanding the difference?
I don't see any of the current 160, 168, or 175 beating him. The best chances I would give: Cleverly, Kessler (healthy and now knowing what he is up against), and perhaps Froch if it is in Nottingham. Hopkins would lose. But it would probaby be an 8-4 fight where he would hold his hands up before the scores are read. Martinez is small for 160 and at 168... well Ward is already technically good enough to beat Maravilla, and now he would also bully him physically. Actually I forgot one guy.... and he may be the one with the biggest chance of them all.... GGG. It is still a puncher's chance, but GGG always has a good puncher's chance.
