The NHL playoffs are wide open, with many upsets. Teams go far every season that you did not expect. The # 1 team never wins. To apply the logic, you did yesterday of guarantee, or today with impossible out, is over the top. If you waited for that you would never be aggressive, it doesn't happen in a very tight cap, strict, many teams have a chance league. You need to take your chances when you feel your team is good enough to make a run, and then you let the chips fall where they may. By your logic a team would never go for it, because in today's NHL is it very difficult to be an impossible out or guarantee anything.
What's done is done now, so let's see how it plays out. While the moves have grown on me a little bit, I do not believe the Rangers are a legit Cup contender any longer and will most likely lose in round 2 against the Canes, but the NHL playoffs are wide open, so who knows. In a weird way, it is almost beneficial to finish 2nd in the Met as they will play a team from the same group (WSH, PHI, NYI), except TB and Detroit are added if they win the Met. Either way, the Rangers need to focus on playing well and gelling. If they play the Canes in round 2 they'll be a huge underdog, but upsets happen, so drop the puck and go from there.
