TFP Editor-in-Chief David Pagnotta first broke the news on March 3 that the Senators were shopping Spezza, who has one-year remaining on his current contract.
Spezza's deal includes a no-trade clause and he will have a say on where he ends up, if dealt.
On Sunday evening, Sportsnet's Nick Kypreos reported, citing "independent sources," that the Senators were shopping Spezza to teams in the Western Conference.
Though Spezza's salary cap his is $7 million, he is owed $4 million in actual salary next season.
The Senators will undoubtedly require a young center with top-line potential and a top-six forward packaged with a high-draft pick in a deal for Spezza.
While a trade could be completed will before the NHL Draft on June 27-28 in Philadelphia, Senators GM Bryan Murray could wait until closer to the Draft before pulling the trigger in an attempt to maximize his return.
