No, Lemaire is not the Devils' best chance to win a Cup. He's their best chance to get 100-point seasons and division titles in the regular season. But they have zero chance to win a Cup in the new NHL with the Jacques system and this group of players.
Unless Lou and Jacques BOTH have turned over a new leaf (and I refuse to believe it till I see it), this is just more running in place. Too competitive to sink, but no real chance to do damage in the playoffs. I had higher hopes for this offseason after the youth movement.
Why does everyone think they know this guy inside out. Everything I read, from those who are not Devil or Ranger fans, have had nothing but great things to say about Lemaire. I see some using the Wild as evidence that he can't coach in this era, but I think most are forgetting that he took over an expansion team in 2000. Of those four expansion teams, none of them have had the success that the Wild have had.
