This would certainly be a great fight if it happens.

However, I don't think it's the "smart" move for Cotto. He's only had one fight at 147 and if he takes the fight, he's in there with a fast, experienced fighter who's just coming down from 154.

Cotto's smart move would be to fight someone of Margarito's class, and move up to the Mosley level a fight or two down the road.
But if Cotto takes the risk now, I won't blame him.
