Again I say take JF Jacques and try him - at worst he gives the AHL Bulldogs a very solid player 22 points in 33 games. At best he provides the Habs with a Québécois born hard nosed 4th liner with potential to score 5-7 goals and be a good role player.
Grab Stewart off waivers as
well. Buy out Gomez in the off season, sign some UFAs in the off season, draft the BPA in all rounds.
Guys I would target would be Parise (no brainer), Oli Jokinen (big center), Konopka (4th line center, great penalty killer), David Moss (consistent right winger).
On defense - I'd try to get Jim Vandermeer or Johnny Boychuk.
Assuming we could sign a couple of those UFAs, lines would look like this:
Pacioretty - Desharnais -Cole
Bourque - Plekanec - Moss
Gionta - Eller - Leblanc
Jacques - Konopka - White
