The Flames have several players a number of teams have inquired about in the past, such as forwards Mike Cammalleri, Lee Stempniak and Curtis Glencross, though Glencross has a no-movement clause and would have to accept to waive it in order to complete a deal.
While it seems unlikely Feaster will part with Glencross, Cammalleri and Stempniak might be available for the right price. Both players are set to become unrestricted free agents next summer.
Cammalleri informed the Flames in June that he would welcome a trade, if one were to be completed, but wasn't actively pushing for a move.
The 31-year-old is in the final year of a five-year, $30 million contract. While his salary cap hit is $6 million, he's earning $7 million this season.
Cammalleri also has a limited no-movement clause and can list up to seven teams he will not accept a trade to.
Some believe Cammalleri would be quite receptive to a trade to a Stanley Cup contender, but such a move isn't likely to happen until closer to the trade deadline in March.
Stempniak, 30, is also in the final year of his contract (two-year, $5 million deal).
Center Matt Stajan, 29, is currently on the shelf with a leg injury, but the Flames could look to move him later in the season if they're out of playoff contention. He's also in the final year of his deal.
