As of this writing, Dmitri Khristich is without question the greatest Ukrainian player (born and raised there) who 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, once with the Washington Capitals and once 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). 

Jim Schoenfeld is likely best known for his coaching tenure (especially for that altercation with referee Don Koharski, when he allegedly pushed him and called him a fat pig in the 1988 Conference Finals), but he was a pretty good player whose accomplishments were solid.
