The KHL has recently recruited a few NHLers… including Jiri Hudler of the Detroit Red Wings.

I think NHL GMs will likely continue to be a little more weary on picking european players in the drafts because there is a strong possibility and even likelyhood that many young players will opt to play in the KHL.

There are differences for sure between the 2 leagues… and one that could help draw players is taxation on salary. Many contracts I’ve read about for players going to the KHL are tax free. This makes a big difference for the KHL teams in helping them be willing to match or even outbid NHL teams for certain players.

RDS is reporting that Plekanec acknowledged that he did receive offers from the KHL but wished to play in the NHL.
