Tampa is already behind cap wise.
They have two tiers of players they can move to free up cap space. Everybody else has trade protection.
Kucherov, Point, Vasilevskiy.
And then,
Gourde, Miller, Callahan
They already need to move two of the second tier just to pay Point. It's possible that Gourds already has a NTC since his contract was a UFA contract and sometimes players have NTCs retroactively added .
If they want a big FA like Panarin, Duchene, Karl, not only do they need to move Miller+Callahan, but they probably have to move one of Kucherov or Point. I guess if they could get something like Hughes for Point and then double dip by signing Karlsson or Panarin with the 10M freed up by not having to sign Point, maybe that makes sense, but that NHL 19 type of wheeling and dealing rarely happens.
