Very different styles. Chuck was loose and long with punches and Wandy loved to swing. Rampage preferred a tight guard and short punches, mostly hooks, which didn't take advantage of Wandy's openings. Chuck would have knocked his fucking head off with shots straight down the pipe. Wandy almost got KO'd by Shungo Oyama that way ffs, lmao.
Wanderlei could have not fight in the octagon nowhere near as effective as in the ring. He could have not pressure opponets in such open and big space where opponents could easilly eavde his strikes and counter him when he misses. Key for Wanderlei's game was the pressure, aggression, speed he threw 2 stikes for each 1 of his opponent, and would simply overwhelm them when they had nowhere to escape in the corner or on the ropes. Simillar to Cro Cop, Wanderlei is a ring fighter, who is handicapped in the cage. In Pride i belive W. Silva would have overwhelmed Liddel and KOd him.
