Why wouldn't Columbus just make that deal directly with Anaheim?

Maybe Anaheim doesn't want Laine or they want Hronek more. They have a bigger need on defense than they do up front. Or Laine doesn't want to go to Anaheim but is open to Vancouver. Or Waddell wants the extra year that Garland brings. Carolina had interest in Garland in the past he might like the player.

All questions that none of us have the answer to.
