Here's what I find humorous in this: we're talking about a guy who's currently 8th in career goals scored in the NHL, and the best argument you can make for why he's not that good is "well, when he wasn't leading the league in scoring he was getting beaten by bums" and "back then there were a whole bunch of HOFers at the top."
It ignores that he's been in the league 14 years and he's led the league in goals more often than not, and he might well do it yet again in year #15. That alone should be enough to put this "he's not so good" talk to a halt ... but it's not, so we go on.
It ignores that 1.5 of those times he was topped by Crosby who's clearly headed for the HHOF, 1.5 of those times he was topped by Stamkos - who for the uninformed has 419 goals and is averaging over a PPG for his career, stats which are going to land him in the HHOF - and two of the other three he had 52 and 46 goals and got beaten by guys who had monster career years. (And Perry had a career year buoyed by a 19 goals in 14 games run at the end of the 2011 season - plus a pair of goalless games at the end - to push by Stamkos for the goal-scoring title in 2011.)
It ignores that he's 3rd in career PPG, only 6 behind Brett Hull and 15 behind Dave Andreychuk, and he's very likely to pass both of them in fewer GP.
It ignores that he's done all of that in an era where scoring is at least a goal and a half behind the high-flying era of the 80s where 50-goal, 100-point seasons were significantly more plentiful.
It romanticizes McDonald's 66-goal season and that he's a HOFer, ignoring that his last 3 years (age 33-35) he had a grand total of 35 goals in 169 games and was a shell of his former self and needed every last one of them to get to the magical 500 mark. (It's also fair question whether McDonald gets in without 500 goals and the Cup win in 1989; he was a 2nd-team All-NHL selection twice, never a 1st-team pick, and only ever got votes for a major award the year he potted 66). Ovechkin, at age 33, had 51 goals last season - or 16 more than McDonald scored dragging himself around the ice the last three years of his career - and has another 40 right now and was over 500 long before that, and was a 1st-team All-NHL pick last year for the 8th time in his career.
It assumes that stats are stats are stats, and zero context needs to be taken when comparing stats from different eras. See my example above.
Finally, it pretends that anyone is claiming Ovechkin is comparable to Gretzky or Lemieux, which no one has been doing. (Reminder of who the measuring stick is right now: a guy known for being a premier goal scorer in league history, not guys who were known for being premier offensive playmakers who could also score at will in their prime.) Keep the focus on the right reference point; don't make up straw men.
