Like I said elsewhere, If Rosado has the discipline to stay outside, and also keep up a heavy workrate, he has a chance to win a decision. - And even if he lost, it would be very impressive, showing us a side of Rosado that we haven't seen before. If this happens, it could be a great fight and also a good test for Golovkin.
Except that's not likely to happen. Rosado loves to bang on the inside too much, which is exactly what Golovkin wants. I don't think Rosado's gonna' be able to stop himself. It should be target practice.
