Tszyu has made his money and lived up to his potential; there is nothing left for him to prove...

But if he comes back; can he boil himself down to 140?

And there is no point having 'warm-ups'; he may as well go for the big fight straight away. He has shown in the past that he can come back well from long breaks... but he was a mere 35 then... he is 37 next month
