This is how Mikhailov did internationally in his MVP winning seasons compared to a prime Marcel Dionne.

Boris Mikhailov 10 gp, 9 g, 3 a, 12 pts
Marcel Dionne 10 gp, 9 g, 3 a, 12 pts
Challenge Cup 1979
Boris Mikhailov 3 gp, 3 g, 0 a, 3 pts
Marcel Dionne 2 gp, 0 g, 1 a, 1 pts
WHC 1979
Boris Mikhailov 8 gp, 4 g, 8 a, 12 pts
Marcel Dionne 7 gp, 2 g, 1 a, 3 pts
Total
Boris Mikhailov 21 gp, 16 g, 11 a, 27 pts, 1.286 ppg
Marcel Dionne 19 gp, 11 g, 5 a, 16 pts, 0.842 ppg
Now the sample size is quite small and I am definitly not saying that Mikhailov was a more talented offensive player than Marcel Dionne and I highly doubt that Mikhailov would ever have won a Art ross trophy. Especially considering that he never led the soviet league in scoring, although he was very close on a couple of occasions (75,78). But I still find it impressive that Mikhailov at age 33-34 managed to put up a combined 1.286 point per game during these 3 tournaments while Dionne at the age of 26-27 "only" managed to score at a 0.842 point per game. And I personally think that it is very likely that Mikhailov would have been a consistent top 5-10 scorer and top 3-5 goalscorer if he had got the opportunity to play in the NHL. And when you combine that with great leadership and physical play you have got yourself a extremely useful player.
