There aren't any official rules regarding LTIR and the salary cap at the moment, so the Leafs are technically not guilty yet, however, if it's determined that LTIR was brought up at all in any of their contract discussions, that's where they could face punishment. For now, we will all have to wait and see how this Tanev situation plays out, and whether he ends up going on LTIR at some point, but you best believe Gary Bettman will be discussing this issue at the next CBA bargaining sessions.
