You are including 2012-13 season with 1.17 PPG, his last entire season was 1.17 PPG also has first season with 1.31, so 6 elite seasons as an elite point producer, and another 6 seasons PPG+, and 3rd all-time harware, and the greatest goalscorer all-time.
It's more than enough to be at least top5 all-time.
The 12-13 shortened season with an unbalanced schedule is a bit of a joke though as he beat up a very weak Southeast division with a line of 18-16-13-29 (+10) line and against the other 2 divisions he had a 30-16-11-27 (-8) line.
His first and second seasons add to to his 5 year prime for sure but last season even with his first 2 month aberration it's a stretch to call him an elite player that year.
Heck he isn't even the best player of his generation and it's debatable if he is even a top 5 player since expansion really.
I think people get too hung up on the "best goal scorer" argument then forget it's a complete player or overall argument and then his case really starts to slip.
I mean in 13-14 he led the league in goals and was a PPG player but also had the worst +/- in the league overall and his 5 on 5 play simply hasn't been that great at all after 2010-2011 as he simply tilts the ice very little for a on the surface superstar.
This season he simply hasn't tilted the ice aside from one period against my shitty Canucks team even with an outrageous usage and PP TOI.
