course he would, Haney would have been the only threat, provided he stayed injury free. Imo apart from having more detailed hams, peak arnold trumps him anyway and with time arnold would have been able to bring out those details.
Personally Arnold and Haney are the pinnacle of the Mr O, after them we got missing biceps, guts, bloat, bloof etc etc
Wonder if Arnold would have still been winning the Mr. O well into the 1980's?
