Is Grabovski on the trading block?

Darren Dreger reports from Insider Trading that the Leafs have received an offer for Mikhail Grabovski.

From @DarrenDreger:

For those unable to see Insider Trading. Offer for Grabovski is for a 2nd rnd pick and prospect. Could get more. Still hope to re-sign him

Is Grabovski really on the trading block? After all he is the team's best centre. Or is the leaked information a negotiating tactic by the Leafs to bring down Grabovski's price?

Grabovski becomes an unrestricted free agent on July 1. His current contract pays him $2.9 million per season and supposedly his agent is looking for an average salary over $5 million per season. That brings him up around Kessel's salary of $5.4 million per season. He does compare to Montreal's Tomas Plekanec who earns $5 million. Obviously Burke prefers to re-sign him and would like to get a home team discount.

If the parties aren't far apart then I see a contract being done eventually. The Leafs are still looking to strengthen up the middle so moving Grabovski only weakens them at the position. But if Grabovski is asking too much then Burke will not hesitate to make a move.
