That's too bad. He really seemed to come to camp busting his ass to earn a spot, and did. But Lafferty especially just sealed his fate as a much better version of him, pretty much exactly across the board.
But he really is more of the sort of..."filler" guy who just doesn't have any particular standout skills. He's not terrible at anything, plays hard, but not really good enough to set himself apart in anything or make himself indispensable either.
So the Oilers putting in a claim would make complete sense. They seem to love staffing their bottom-6 with guys like that. He'd probably even be an upgrade on several spots.
Hate it any time you're losing useful depth though, while trying to shuffle the roster to cover for injuries at a different position or whatever.
