Bad stylistic match for Gerald. He used his jab as a range finder while circling, in order to land that amazingly timed overhand right followed by hook to body, and Ward would take away his jab by staying out of distance and smother him in-close
If a naturally bigger guy and puncher like Kovalev wasn't able to stop Ward then G-Man won't do any better at all. After the first few rounds and a shaky round Ward will slowly dissect G-Man, taking away his power, and win in a lopsided fight. G-Man didn't have much in-fighting skill and Ward was a master at controlling the distance.
