I've heard through sources I trust that behind the scenes the Avs are doing everything they can and are exploring every option (including some very creative ones) to rid themselves of Nuke and his contract.
It ain't easy, and there are more than a few moving parts. Addiction is a tricky condition to navigate under the law and the CBA. Serious enough to require accommodation and time off under the CBA, but tough to LTIR - you have no idea when he'll be declared ready to play. It's not like a ACL or (cough, cough) a ruptured spleen - there's a recovery timeline for that. Plus state and federal laws kick in (including HIPAA) that prohibit employers from commenting publicly.
I get so tired of columnists and others complaining that the Avs "enabled" Nuke and/or swept stuff under the rug. Under CBA rules, the Avs were required to get Nuke into the recovery program. Under state and federal employment law (including the ADA), substance abuse can be considered a "disability" , so that plays into it. Under either scenario, HIPAA prohibits public comment about it. Believe me, if CMac went into any substantive detail about Seattle, Nukes lawyers would have sued the corpuscles out of Kroenke.
