Since when are generically elite players on pace for the #5 player all-time?
#5 in what sense? points per game?
first of all he's 6th right now
second of all it's a lot easier to have a high points per game when you're missing a bunch of games than if you're playing full seasons,look at Crosby's points per game in his full seasons once he got after his injuries compared to his much ballyhooed paces,look at the high points per game of other players that missed lots of time like Forsberg(top 10!) and Lindros etc
third and probably most importantly he's only 31 right now,career points per game paces go down fast as you age and your production declines and he's got a lot of that ahead of him before his career is done
just as an example say Crosby plays 7 more seasons and averages a point per game(some above some below as he continues to age),all of a sudden he's 14th in points per game instead of 6th,and all from playing to a normal age at a super gentle decline,he could very easily play longer or decline more or both as well
there's a reason Mike Bossy is third all time in points per game and it's not just an era thing
