I don't know why Valero hitting harder than Pac = Valero beating Pac, or even giving Pac a tough fight.

Valero had power that was off the charts, that much can't be denied, but I remember a guy who's technical ability had diminished and relied heavily on landing the big shot (not a great strategy to beat Pac). I remember him taking a lot of punishment from much lesser fighters who had the balls to stand up to him, like Mosquera.
