no reason to trade Stone, those contracts are probably higher then what they will sign for, if not Stone can just play in minors

We have to trade a few people. We have no room.

I'm going by numbers relative to what other similar players have signed and then scaled accordingly. We are going to have to pay more than the salaries I've been seeing here; this is me calling it.

According to EW's 2019 contract projections, which have been fairly accurate so far:

Bennett - $2,795,669 x 3 years
Mangiapane - $908,833 x 2 years
M. Tkachuk - $7,836,132 x 6 years

Rittich was not listed, as no other goalies were listed, but he will receive no less than Talbot and likely not above 500k more so to be safe lets go with the max.
Rittich - $3,250,000 x 3 years

TOTAL = $14,793,884

Currently the flames have $9,973,292. If we trade Frolik only that gives us $14,273,292 in cap space. putting us at -520,592 and a 24 man roster. since the max roster is 23 one of Quine, Dube or Mangiapane will be sent to minors freeing up at minimum $735,000. Thus putting us under the cap,

Personally i think they will sign for these numbers:
Tkachuk: 8M x 7/8 years
Rittich: 2.75M (match Talbot) - 3M x 3 years
Bennett: 2.5M - 2.75M x 3 years
Mangiapane: 975K x 2 years

TOTAL = 14.225min, 14.725max
Both totals are still below the cap from just trading Frolik alone.

Sure if we can get value for trading Stone then go for it but he might be playing on our 3rd pair this year

Any package for Ehlers would probably include Hamonic (coming home)
