The first day of NHL free agency brought with it a whirlwind of activity, as a number of high-profile free agents changed teams.

They inked former Ottawa Senators defenseman Wade Redden to a lucrative six-year, $39 million deal, a move that unquestionably upgrades their blue-line corps. Redden is one of the league’s most talented puck-moving rearguards, and should provide the Blueshirts’ power play with a much-needed boost.
