I'd have to agree that it's a toss up at 147.

Cotto looked more comfortable at the weight, but this is comparing both fighter's performances after only 1 fight each at WW.

That's not really a definitive indicator of what the outcome would be.

Sure, Hatton decided to fight next back at 140, but that still doesn't say how the fight would turn out at 147 between these two.

The only thing I would feel very confident about predicting is that, at 140, 147, or even a catch weight, these two getting in a ring would make for one hell of a night of boxing. My prediction would be that someone gets KTFO.
