Here is how it affects the Kings, and why they may have preferred Durzi over Lilegren even more.
According to Sportnet. For Seattle in the expansion draft. Here is who they can and cannot pick.
Players with no-movement clauses will be protected automatically. Also,
any first- or second-year professionals and all unsigned draft choices are exempt.
Seattle's possible NHL expansion draft would have same rules as Vegas - Sportsnet.ca
I think this includes AHL, and not only NHL. The AHL is a pro league, and Lilegren and Sandin will have played including this year . 3 pro years of hockey by the expansion draft.
Durzi played in the OHL this year. He will be draft exempt. The Kings may have out foxed GM Dubas. Not that they preferred Lilegren anyway, if they had taken him. They may have been in a position of leaving him unprotected in the expansion draft.
If this is so, the Muzzin trade with Durzi's all star performance in the Memorial Cup, Grundstrom's early promising start, and the still to go #22 pick, just may be a slam dunk win by the Kings over the Leafs.
