Clottey fights a more disciplined fight than Cotto. He fights behind that high guard. He fights in spurts and when he lets his hands go, his combinations come fast and are accurate. I don't see him getting hit like Cotto did, at least not coming and while being wreckless. I just think Clottey is going to fight a solid fight. Probably lose on the scorecards 8-4ish. But i think people just underestimate Clottey. They look at his shortcomings but fail to see his strengths. To answer your question, yes, of course it's possible.
at this point i'm really not comfortable saying pac can't do anything. he's definitely capable of hurting clottey, but i really don't think he's going to KO him.
I say no, Clottey just seems like a tough Mofo! But that doesn't equate to a Clottey win necessarily!
