Just one case, but former Cat Tony Kitt use to play in the Netherlands (if I recall correctly). Knew some guys who played intramural hoops in Manhattan with him during his offseason. Tony is just another in a long line of former Cats that love MHK. Said he had around a 50 game schedule...he brought home six figures. Guessing, based on the pay, that this was probably an above average professional league in Europe.
Doubting Travis Canby brought home big bucks playing in some German league...
