While we don't know what might have happened if the Wings had not acquired DeBrincat, I think it's safe to say that trade has turned out to be Kubalik (12 points, nearly zero value pending UFA trade bait), Sebrango (lifetime AHLer), Boston's 1st Round pick (probably late 20s) and a 4th Round pick (almost certainly nothing), for DeBrincat AND the Future Consideration that DBC in Detroit might help sign Kane. And possibly keep him in Detroit for the rest of his career. Which, knock on wood, might be until he's 40 the way he looks now. Showtime: Part Deux.
Pretty good trade.
