He was 171 for one of his earlier fights and 171ΒΌ for his fight prior to the Super Six. He's been bang on the 168 limit for 4 of his last 6 fights and he was a quarter of pound under for the other 2.
He was a 175lber in the amateurs. His issue is that his power is only respectable, rather than being a big puncher. It says more about Chad Dawson struggling at 168 than it does Ward's power truth told, maybe now that he's had his shoulder repaired he'll have more heat.
