I think this is an excellent move. Laviolette is a good coach and a proven winner. The system the Preds have in place now has been good at maximizing returns based on minimal investment, but this speaks to some extra ambition on Poile's part. Sure, they could have kept Trotz, kept drafting well, kept losing their talent to other teams without moving past the first round of the playoffs. It would have worked but stagnation is no way to run a team.
Nashville needed a new voice. Combined with the right personnel moves, this could yield some pretty big results.
