There have been a few trades between the two teams since Bergevin came to the Habs...just none of the particularly relevant variety.
January 14, 2013 - Habs trade Brendon Nash to Florida for Jason DeSantis (the AHL rights had already been swapped a few months earlier)
June 30, 2013 - Habs trade their 2013 7th to Florida for their 2014 7th
July 5, 2013 - Habs trade Phillipe Lefebvre and the 2014 7th they had acquired earlier to Florida to George Parros
March 4, 2014 - Habs trade a 2015 5th to Florida for Mike Weaver
