Iggy fits the requirements of what Burke said he's looking for, and it seems like Sutter and Burke are pretty happy with each others as trading partners.
Grabovski I can deal with, but I don't know why Kaberle has to be included, unless there's more coming back in that deal. People (who make up these rumors) have to realize there's a HUGE difference in trade value between a A/ 35G star forward who has $21M left on his contract over the last 3 years, and B/ a star defenseman who has 1 more year on his contract at a very cheap $4.25M.
Few teams can take $21M contract, and that affects Iggy's trade value. When you carry such a big contract you can never trade him for fair value.
Kaberle's trade value > Iggy's, and for Toronto to throw in Grabs with Kabby to get Iggy makes no sense.
I don't think Burke would even do Kabby for Iggy straight up. Something else's gotta come back to make it work.
