No.
Gretzky had 1963 career assists.
Jagr is 2nd all time in points at 1921. So Gretzky has more assists than 2nd place has points.
Gretzky also played about 250 less games.
McDavid is a great player but no one compares to Gretzky, and no one likely ever will.
Your point while right is presented to make Gretzky look better than he was
Jagr is a fringe top 10 player all time. Comparison with him of course looks bad to the GOAT
Gretzky has 1 rival and that was Lemieux
Lemieux is maybe <5% worse as a player than Gretzky was. Just had horrible injury luck.
Mcdavid is probably going to end #3 all time and be <10% worse than Gretzky. He has a chance to be in same tier as Lemieux if he keeps this up.
Mcdavid right now is more dominant at his sport than Lebron James was before 2012 when he got his first ring
6 rosses, 5 lindsay, 4 harts he will have after 9 years (assuming he wns this season all 3 which hes on track for)
Lebron got ring #1 in year 9 and then added 3 more along the way. He is in a 1A/1B situation with Jordan for GOAT of NBA with opinions being close
Mcdavid if he adds 3-4 more of these type years and gets 2-3 cups has a legitmate GOAT argument over Gretzky
