Naw. DLH is guilty of cross dressing to be sure but he won't fight Cotto if Cotto looks **** against Margo. I can't see DLH fixing the decision. He only does that for himself. Screw everyone else.
I don't think it will matter too much. After all, DLH still has to make it past Mayweather for this to even be a fight worth making. If DLH does make it past him and Margarito defeats Cotto I don't think it would be very much less profitable than DLH/Cotto.
