Tszyu was 35?? and had fought Tackie Leija and Mitchell, since his biggest win against Judah, so I don't see why he suddenly got 'Old'
Was Lewis old against Grant, Tua & Botha, was Hopkins old against Vanderpool & Echols?

I know Hatton's limitations and I have already said I think he would lose to MT, but I just don't see any eveidence of Tszyu being old (other of course from the fact he lost to Hatton - so I guess he must've been )
