The Rangers captain would be able to help the B's in every aspect of the game, with great leadership, character and he can put some numbers on the board.
The problem of course would be the cost to land McDonagh, Shinzawa points out the asking price is likely a first round pick, a young NHL player and a prospect, a price which is likely way too high for the Bruins.
However, the Bruins are arguably one of the best teams in the NHL right now with a serious chance at a Stanley Cup run, with McDonagh still signed for another year, the price might be worth.
