The Sharks will if they think Trouba can help them compete more (which is a reasonable thing to think). They already did it with Goodrow and his contract. It would make sense to claim here too as a means to get something for doing the Rangers a favor then. Goodrow probably doesn't have trade value but Trouba probably would on his last year.The waivers thing feels like a pretty empty threat. Who’s gonna claim him at his full salary/cap hit?
