I think you're making something out of nothing. Two minor incidents leads to Ray Emery? Emery was a headcase and was part of a bad clique in Ottawa.
Also, there is no negative media attention surrounding him. Lehner has handled himself very professionally this year besides that one WJC rant. He will have no effect on players competing for jobs anyway, he's a goalie.
Not saying the guy is perfect, but he doesn't have to be.
