I dont know if it was previously reported on the board as I am new (Hi everyone first post ) but I remember reading earlier this summer that Rachunek signed an exclusive contract with a foreign team and would not be able to play in NHL this year. Sorry I know a link is needed but I do not have one. I read it in the Journal News a couple weeks back.
The pending IIHF agreement will allow for contracts to be signed with any European player regardless of their contract situation with their current European club. That is why Rachunek is still a question mark - it's likely a bargaining chip on his behalf to get more money (or a trade) out of the Rangers.
