Perreault was notoriously unselfish both as a shooter (pass first mentality) and as a player who wasn't really driven to put up big numbers. Not saying that as an excuse, but as a widely held belief.
And I don't see a whole lot not to like about his production. 1327 points (35th all-time) and a higher point/game average (27th all-time) than MacKinnon, Bure, Messier, the Hulls, Ovechkin, Oates, Clarke, Sittler, Selanne, Kariya, Gilmour, St.Louis, Thornton, Jagr, Fedorov, Mikita, the Sedins and a host of others.
And like I mentioned, he increased his point/game in the playoffs and was a tremendous international player. Only Canadian (and Russian?) player to play in the 1972 Summit, 1976 and 1981 Canada Cups, 1979 Challenge Cup and in retrospect, may have been overlooked for the 1984 Canada Cup (Islander/Oiler split squad, 13th in points/game among Canadian forwards in 1983-84) where he would have been a nice veteran presence with his international c.v.
