He has good power for his size. Nowhere in the leagues of Shane Mosley. If you rewatch the Cotto fight, you'll see the two knockdowns of Cotto happened because he walked into punches he didn't see coming.
no. no shame in that either. i think pacquiao would struggle to knock down most at 154, let alone at middleweight. much of pacquiao's power is generated from his handspeed and great timing. if he got fat, and lost some of that speed, his power would subside drastically. whoever mentioned pryor made a decent comparison.
