The league over here isnt that great, though it's often underestimated anyway. This year we had a few AHL guys, a few NHL drafted guys, but most of the non-dutch guy are below that level. ECHL guys can usually get along in the league quite easily.
Den Haag has been the worst team this year by the way. But with a few nice additions they might be cruising next year.
I'd suggest to take a look at this link here and see what the resume is of the non-dutch guys mentioned there. It might give you an idea!
