I'm pretty sure Erik Ersberg just won the (Gagarin) Cup
But it's hard to tell. Jan Marek, at least, I know played in the game, because he's on the score sheet (for the losing team). Erik Ersberg, I believe he played just under 40 games for the champions -- Salavat Yulaev Ufa -- but I could be wrong. Here's the link to Ersberg's KHL page.
Marek, by the way, came the Kings' way in the Sean Avery trade, but (if I remember correctly -- too lazy to check the old Inside the Kings archives) turned down a Kings contract because Lombardi wouldn't guarantee him a roster spot. Something like that. He is one of a handful of draft picks playing in Europe whose rights the Kings control should any of them ever decide to come (back) to the NHL, which they never do.
In other news, Wikipedia lists Ersberg as 6 feet tall.
