I think it was the result of a bunch of factors.

First, the ring-rust was obvious and I think that his team might have overtrained him in an attempt to compensate. Second, he's had trouble with high-volume pressure fighters in the past and Molina didn't give him room to breathe.

However, I think the two biggest things that worked against him last night was the perception of his opponent and his confidence. I really think he probably looked at Molina's record, his lack of power, and his lack of experience and expected the KO just to come to give. As a result, he constantly threw one-punch at a time, neglected his jab, and basically became an incredibly one-dimensional fighter. Then, when it became obvious that Molina was the real deal and that Cintron's timing was way off, I think his confidence, something he has always - and quite visibly - struggled with just disappeared.
