Barkov or Kopitar with 125pts please
That's the thing - current day Barkov or peak Kopitar is close enough to this. Maybe +/- 20 points, but I don't see a huge upgrade on the quality of a Barkov/Kopitar. Great players of course, but with options 2 or 3 you're talking Orr++ or Hasek ++. This option is easily last.
The D is equal to Bobby Orr, easy choice
Equal or better to Orr. 50 goals throughout his prime? Orr in reality only once went above 37 goals, and never reached 50. I know he did surpass 100 points often, but it was a higher scoring league. The way OP describes this player, I have him equal or better than Orr.
Problem is - I wonder how good the goalie also is. Hasek in his 6 best years (94 to 99) has an average of 929. If you remove 1996 (his worst season in that stretch), it goes up to 932 sv%. And that's in a much lower scoring era (dead puck era years) than today. 935 sv% average in today's prime would be well above and beyond Hasek, so the best goalie of all time by a big gap.
Carey Price won the hart and lindsay and vezina in 2015 with a 933 sv% (also lower scoring year). It would be equivalent to a goalie's prime being superior to that season, each and every year.
Assuming the goalie is also good in playoffs, I think I go goalie first, defenseman second, and forward last.
If there's a risk goalie is a choker come playoffs, than I easily go defender first. But with no mention of playoffs in OP, I'll just assume all 3 players do well enough come playoffs.
TLDR: My rational is:
Player 1 > Barkov/Kopitar. A bit better than them
Player 2 >= Orr. Equal or better than Orr
Player 3 >>> Hasek. Much better than Hasek, or much better than peak Price (every single season).
I go Goalie > Defenseman > Forward
