i feel Nunn gets overrated by some. Looked great against Tate, bur what did Tate really do? Fantastic KO of Kalambay, but with only those few seconds to go by it's hard to say how much a fluke it might have been. Roldan and Curry: Solid wins, but against past it opponents. Could have lost against Barkley and while I haven't seen the Starling fight I understand it was close. Toney exposed the flaws in tempo he showed against Barkley and the flaws in defence his legs had glossed over so far.
Nunn by decision Too fast and fleet of foot, plus unorthidox lefty stance. McCallum would be a step behind all night.
McCallum did tend to have more issues with clever boxer types. Kalambay beat him and Graham pushed him very close. Nunn on points though if he gets careless McCallum can end it.
