I don't think he even needs to score 150 points....we've already seen what McDavid can do, so anything fairly close, for multiple seasons, will do the trick.
There has already been people declare that McDavid is the best hockey player ever....so I assume this will continue, especially if he puts up a few seasons of 140 points, or whatever.
For younger generations, it's likely we're going to see a Big 6 emerge in the coming years....i.e. their current Big 3 - Gretzky, Orr, Lemieux - plus McDavid, Ovechkin, Crosby. Especially if Ovechkin sails past 1000 goals (which looks possible), and Crosby continues to put up significant points into his 40s (which also looks possible)....and if McDavid continues what he's doing now for several more seasons.
As is always the case, there are generational differences of opinion of this stuff....but it's clear that the O6 guys - Howe, Hull, Beliveau, etc. - will continue to fall among the hockey world as a whole.
I think Howe for the most part is still recognized/respected by younger fans. He's Mr Hockey for a reason. Heck, just wait until the new DET/Windsor bridge is complete; its named after him which will keep his name in conversations.
