I also tend to favor complete players, but at a certain point the offense is just too great to overcome. Additionally, lost in this (overthought, or underthought, it matters not) is the usage of possession as a strong form of defense.
Examples: 2012 Devils. Obviously, it's been a long time since the Devils were this 1-2-2 dominated team. Instead, they utilized an aggressive three-man forecheck, proper puck support and cycle game to prevent opponents from gaining meaningful attack time. The opponent spends 45 seconds chasing them around and trying to loosen the puck from the boards that by the time they free it, the shift is over and they have to dump it in. Meanwhile, a properly executed cycle allows for players to filter off on a change "behind" the play ensuring fresh troops can continue possession or re-acquire it. Moral: possession time matters, and can be an effective way of keeping the puck out of your own net...what players were better at keeping the puck than 66 and 99?
While Lemieux wasn't going to get any Selke votes at any point in his career, he was just too dominant to ignore. Similar to the goalie project, I favor technique a lot because proper technique allows for adaptability and sustainability. But I still had Dominik Hasek at #1 because it was just too good to overlook. He didn't do it "right" but he was so amazing at doing it wrong in different circumstances that you can't ignore it. Mario was so good at dominating the play that you can't ignore it.
I just can't envision a reasonable scenario where Gretzky and Lemieux aren't 1-2 in some order, just my thoughts on it.
