For the New York Rangers, first, it was Ryane Clowe. At the 2013 Trade Deadline, the Rangers acquired the forward for 2nd, 3rd, and 5th round draft picks. Clowe had zero goals at the time of the trade, while the Rangers required far more offensively gifted players.
The acquisition of Clowe did little for New York, as expected. Clowe chipped in 3 goals in 12 games, then failed to score in a pair of playoff games. New York was eliminated, and Clowe bolted for the New Jersey Devils. The result of the trade was the loss of assets for a player that never belonged on the team.
