Carolina missed the playoffs the previous two years under Laviolette also, however. So it's not like they suddenly turned into garbage just because they fired him. In fact, Maurice replacing him was their only positive, minor cinderella run to the semis after replacing Lavy, sandwiched between a pair of playoff misses on either end under each coach.
And Philly also missed the playoffs the season before Lavy was let go. And subsequently made it the season he was canned under Berube.
So I'm not sure there is any basis here for thinking that Lavy was somehow propping up his teams? They both actually improved immediately after removing him, no?
