Actually, it is a conflict between Jake Trouba and the Rangers. When he blamed his performance on his injury, he inadvertently made Drury and Laviolette look like idiots. The only he could make up for that portion is by helping the team win in the ice. Win, and everything else falls into place.
Assuming that neither party can repair the damage, the situation can't linger into he season. If Drury waives, trades, or buys out Trouba, then he should do it before training camp.
