two things need to happen to make this better
1. games played after a certain age need to be excluded. Bure didnt play any old man games that dropped his average. Neither did Bossy. Perhaps 32, or 34. in there somewhere.
2. When they played needs to be adjusted for. There is a reason Blaine Stoughton, Denis Maruk, Jacques Richard and a slew of others had better golascoring seasons that Crosby, Kovalchuk, Iginla, etc. and it isnt golascoring ability. Bure scored a lot of his goals in a very hard to score era. Ovechkin less so, but still much harder than most of Wayne and Mario's goals and every single one of Mike's.
Bossy actually gets the benefit of every angle in this current format - retired early, all games played in a wide open league, great centreman and team around him.
edit - this talk remonds me that Hasek, of his career is cut off at a certain age, was a career .926%! Of course this slowly dropped as he played into his 40s.
