As of this writing, Dmitri Khristich is without question the greatest Ukranian player (born and raised there) that ever existed in the National Hockey League. The native of Kiev was a two-time NHL All-Star (1997 & 1999) and was a 70 Point scorer twice; one with the Washington Capitals and one with the Boston Bruins. Khristich also played for Los Angeles and Toronto over his 811 Game NHL career.
While Jamie Macoun could be accurately described as a stay-at-home Defenseman it just does not seem enough, as he was so much more.
Falling six points shy of 800 over his NHL career, Ed Olczyk would play for six teams in the league, the best of which was when he would score 75, 90 & 88 Points respectively in his three full seasons with the Toronto Maple Leafs (1987-88 to 1989-90).
