In October of 2013, Garth Snow made a bold move trying to put the New York Islanders over the top. He traded Matt Moulson, a 2014 1st, and 2015 2nd in order to land Thomas Vanek from the Buffalo Sabres.
At that point, Vanek had two 40 goal seasons under his belt, and he was coming off a season in 2012-2013 where he had 41 points (20 goals, 21 assists) in the league shortened season.
Before John Tavares got hurt, Vanek, Tavares, and Kyle Okposo formed one of the more potent top lines in the league.
