OK, so under the nhl rules this trade is legal. Its a new version of the tampa thing with Kucherov
So grab a high price ( last year of contract) make sure he cant play for at least 6 month maybe 8 months so the INS pays him and you get cap space and you still dont have to play him in the playoffs.
SO why not take this 1 step forward. sign 3-4 top players, accidentally break their legs so the INS pay them and then suddenly bring them back as the playoffs start. Would this STILL BE LEGAL under the current rules. I know sounds crazy, BUT that is NOT MY QUESTION, would it be LEGAL.
