I maybe wrong, but I didn't think college players were subject to that because they can play in the AHL. Players in that age group that come from the CHL cannot play in the AHL and are returned to their CHL teams if they're not kept on the NHL roster. Because Keller played college he can play in the AHL thus negating that contract slide. Not sure about this or how to verify, but that was the way I understood it. The 10 games is if a CHL player plays 10 games or more and then is returned to his CHL team he still burns a year of his contract.
