IMO, playing on the same team as Gretzky held back Messier's regular season numbers a little bit. Overpass showed that Messier didn't get much PP time until a year or two before Gretzky left.
It's also no coincidence that as soon as he was separated from Gretzky, Messier immediately became a threat to win the Hart trophy, winning it in 1990, 1992, and runner up in 1996.
not saying mess wasn't a great offensive player and very successful even without gretzky - but i think soemtimes people forget
how much gretzky was better than everyone else. that gap was enormous and something the game will probably never see.
from 80-81 to 86-87 gretzky outscored messier by 101,124,90,104,154 (mess played just 55 games),131,75.
he outscored not just messier but this vast amount - but the whole league. Outside the oilers players (who were riding the gretzky wave) in those same years gretz outscored the next highest non-oiler by:
65 (bossy)
72 (stastny)
84 (goulet)
78 (hawerchuk)
64 (mario)
76 (mario)
the numbers are far too staggering to ignore, especially when it comes to the statistical impact on other oilers players.
don't want to take anything away from messier. As you said, he went on to have an incredible career even without 99, but gretzky didn't "benefit" from the 80s high-scoring era - he CREATED IT.
way off topic now, apologies!
