We don’t need the cap space that badly that we trade Burakovsky and not getting a somewhat adequate replacement. Vegas isn’t going to trade one of their prized prospects for Kane. They won’t sacrifice a key piece of the long term future, no matter how good they think their Cup chances are

Dude Larson and Beaulieu I'm dying

vegas will not do that trade or washington
kane is also going into free agency

If Caps made a trade with Buffalo, it'd probably be something small for Pouliot. maybe a mid level D prospect and/or a mid round pick

Don't think the Caps make that deal this season, but in the summer there could be deal for Oprik and a sweetener to the Sabres

Kane is worth that value on every team except Vegas. They are not going to give up future good players for Kane, even though it would make their team even better.v
