Two things.
1) 8.6.(c).(ii) of the CBA stipulates:
If a Player drafted at age 18 or 19 is a bona fide college student at the time of his selection in the Entry Draft, or becomes a bona fide college student prior to the first June 1 following his selection in the Entry Draft, and does not remain a bona fide college student through the graduation of his college class, his drafting Club shall retain exclusive rights for the negotiation of his services until the later of: (a) the fourth June 1 following his selection in the Entry Draft, or...
The remainder of this is frankly irrelevant.
- Werenski was actually 17 when he was drafted, but 18 as of September 15 2015; for the purposes of the CBA, he was 18.
- He was a bona fide college student.
- If he leaves, Columbus retains his rights through June 1, 2019 even if he leaves to play junior hockey. This is the same thing that happened with Peter Quenneville, as accurately reported by me earlier this year that was apparently unknown to even the team's front office.
2) My second thought is this: something has to be done pronto about the CHL/NCAA Cold War. College teams are either losing committed recruits to the CHL before playing a game, or losing players in the middle of a season to the CHL. And because of the split on amateurism, it can't flow both ways.
Ideally the CHL would simply sign an agreement not to poach committed recruits or active players, but I can't see that happening.
