There is always Sprukts, who was released by a Danish league team just to make his way to the NHL in a couple of years..
Sprukts did produced 12 points in 15 games for Odense. I thought it was because of lack of finances.
Alexander Macijevskis played for Odense and was most likely the cause Spruks came over to the club in the first place.
But this article supports you are right
Quote: "spilleren som OIK ikke var interesseret i at forlænge med."
Translation: "the player that Odense ishockey Klub wasn't interested in prolonging [the contract] with".
"Good" job Odense
But it is not the worst a danish club has done in sports:
Brøndby said no to Luka Modric twice!
In 2003 a 100.000 Euro offer from his agent to several Danish superliga clubs (!!) and again in 2005 to Brøndby for 1,25 mil Euro. They felt he was to small and not good enough
In 2008 he was sold for 20 mil Euro to Tottenham and went on to Real Madrid.
