I was just excited to have an excuse to post that after spending a good chunk of my first day back at work making those lists for every team,
Let's go with Horvat since he actually would move the needle and would be worth it for them to move money around. For argument's sake, they trade Lafreniere and Chytil for Horvat. Or they trade them for picks and sign Horvat as a UFA. Either way, Bo signs with them for 9m. Miller gets a 2.5m bridge deal. That leaves them with 6.1m for a back-up goalie, 3 bottom of the roster defencemen, and 5 forwards. It's tight and would mean they are basically icing a bunch of Jimmy Veseys and Ben Harpurs but barely doable.
Buy yeah, I don't see the Rangers as a good trade partner at all. There a bunch of other teams with ample cap space for next season that are much better targets.
