Suzuki, 2nd, Tatar for a disgruntled Pacioretty
Armia and 2 picks for Bourque
Danault and a 2nd (Romanov) for Fleishmann and Weise
Byron off waivers
Allen and a 7th for a 3rd and 7th
Turned Galchenyuk into Domi , into Anderson
signed Kovalchuk to a cheap contract then got a 3rd for him 2 months later
Scandella for a 4th from Buffalo then traded him a month and a half later for a 2nd and a 4th to St Louis
I could go on. Bergevin gets value from trades. He’s not great at roster construction though (and he was handcuffed by the requirement of hiring French speaking coaches)
