I was very dissapointed with Mosley's jab and defense. He doesn't adapt defensively... he just resorts to a shoot out, and his jab horrible... he always slings it out, but its very easy to block for the high end guys, kind of like Zab Judah's... I think this is why both of them can't keep opponents at bay while Mayweather can. Roy JOnes Jr also through a distance finder jab most of the time, but he threw every punch in the book so effortlessly and quick that he could use a lead left hook or a lead cross instead of a jab.
