I've said this before but Bossy just doesn't belong in this group.
His longevity is relatively putrid (not even 500 career adjusted goals).
His peak is unspectacular - career high of 69 goals in an era where 3 other guys had 85+
His adjusted peak is 7th of this group, and far lower than that really. There are several players from his own era who outscored him in terms of peak season: Gretzky, Lemieux, Hull, Selanne, Mogilny, Kurri, and Nichols. I mean, that is waaaaay too many for a placement this high.
His leads at the 5 and 10 year marks are nice, but not nearly enough to overcome the glaring weaknesses on his resume.
Taken all together, it's just not a good case.
At a minimum, I'd put him behind Ovie, Gretzky, Bobby Hull, Jagr, Howe, Brett Hull, Esposito, and Richard.
There is simply no way the guy is even in this conversation had he played in any other era.
