Back in the Seventies and Eighties when I lived in New York and was an Islander fan, Philadelphia had a power-play specialist who scored a record number of PP goals one season, when added end-to-end wouldn't have gone the length of the rink. He was solid and I think red-headed and would park himself in the crease and my failing memory is that he scored 34 goals that way. Can anybody tell me his name? Any chance it was Kerr?

Google is your friend

I wasnt alive back then but after a quick search for forwards with the most PPG per season playing for the Flyers in the 70s-80s: the answer is Tim Kerr with 34 in 85-86. Nobody else even came close to that with the next closest player, Rick MacLeish, scoring 21 PPG in 72-73

Yes! That's the guy I was thinking of. Can you imagine what a guy like that would command on the market today? I remember Denis Potvin and Kenny Morrow and Dave Langevin and Gord Lane struggling to keep him away from the crease. In those days, referees called many more penalties at critical times in games than they do today. That's what made Flyers-Islanders games such titanic struggles.

Had to be Kerr by your description. The crease was smaller making it easier to crowd the goalie/net. Flyers would have Kerr in right at the crease. Bossy scored so many of his PP goals 25 feet from the net, sorta in the dead zone between the rectangle of the four defenders.
