He has to come in low and work the body hard. It wasn't Rocky's style but i would try to use psychological tactics. I would get Rocky to throw left hooks while screaming the name "Lamon Brewster". It might make Wlad even more gun shy. Honestly, much as i love Rocky and dislike Wlad, this is a bad stylistic match up for him. Marciano never faced a puncher like that and his short arms would make it hard for him to land cleanly. Marciano's best chance is to attack the body, use psychological tactics to make Wlad more hesistant, fight dirty if Wlad tries to lean and clinch, etc.
