Only one? Nahh I see Judah winning this one VERY early.
I said in one of the Judah-Cotto prediction threads that Judah takes it in 2.
I'm not suggesting that Judah wipes him out easily, mind you.
I just like Judah's ability to start quick and land effective punches early in fights.
I couple that with Cotto's chin, which I am not 100% sold on.
Judah tags Cotto in the second, Cotto gets up from it albeit groggy and legless, Judah goes to town on a wobbled Cotto, ref stoppage, TKO in 2.

Note: I like Cotto. It's just a prediction.
