Dela Hoya with his come pressure attack showed us Mayweather is vulnerable. Shane showed us in his fight against Margarito that he still has a little left in the tank to get to Mayweather. If Mosley can't get to Mayweather by the 7th or 8th, most likely a KO won't happen and by then Mayweather should be able to control the ring if Mosley doesn't have any legs left. If Mosley get's to Mayweather with a few good shots early, I don't see Mayweather controlling the fight and certainly there is no way he can control a bigger fighter like Mosley like he did Marquez. I see Mosley winning a unanimous decision. 8/7 rounds to 4/5.
