In that case, Drury probably decided he would rather buy him out or bury him than give up an asset to dump him.
Hard to see Goodrow being mad at the Sharks for picking him up... At least he's wanted here, probably earned him a bunch more millions than he would have if he cleared waivers.
Still an open question whether Goodrow is a better player than we could have gotten in FA and there's an active debate here about whether his cap hit matters or doesn't matter, whether he's overpaid or not in 2 years, but if this report comes out, I think we can probably put to bed the idea that Goodrow is mad at Grier/Sharks.
