Maybe I'm missing something, and someone will jump in to help out.
Assume the cap goes up to $84M next year.
Tampa has 10 forwards signed for $50.4M
Tampa has 4 defenders signed for $16.2M
Add 2 Goalies at $4.65M (what a deal)
And 1 Buyout at $1.83M
Totals $73.1M
That leaves Tampa with $10.9M and no less than 6 players to sign. If Point gets a $10M offer sheet they'll need to free up $5M + $1M per player they release. At the end of the day Erne could be the Bolt most vulnerable to an OS.
Trading Miller for futures (which will not be a problem) frees up another $5.25M, giving us $16.15M with 7-8 players to sign. If Point gets $10M that leaves us $6.15M for the other 6-7 players. Which seems like a problem except we’re talking about our botton three or four forward roles and our bottom three defensemen roles. The RFA forwards currently in those roles will not cost much to resign and can easily be replaced from within our system if necessary; replacing the departing UFA defensemen will be a bit trickier as our depth is weaker in that area, but the 6D and 7D roles are not particularly critical and can be filled cheaply.
The only place we will probably find ourselves wanting to have a little more money to spend will be on our 5D - ideally we’d like a decent veteran capable of carrying the bottom pairing opposite somebody like Foote, or possibly to pair with Serg if we decide we’d rather let Hedman or McDonagh shelter Foote (or whoever our 6D ends up being.) Which is why we will probably try to trade Callahan with retention to minimize/eliminate the incentive required to move him while freeing up a few million in cap space to improve our defensive depth next season.
Theoretically we could also trade McDonagh and/or Gourde before their new contracts and full NTCs kick in July 1st. Neither is likely to happen (especially McDonagh) but the possibility does exist.
Anyway the point is we are in no danger of losing Point, and if somebody like Erne were to receive and sign an offer sheet it’s not going to hurt us in any real way. Now next season will be more difficult and possibly more painful as we’ll have Vasy, Cernak, Serg, Cirelli, and Joseph to sign. But that’s a topic for another discussion.
