It was always going to be a numbers game. With six defencemen on one-way contracts plus Jake Sanderson, Lassi Thomson was in tough to make the Sens out of camp. The Sens were stuck in the classic preseason conundrum of having to waive a player, hoping he makes it through because there are so many players on waivers, but it didn't work. The Anaheim Ducks have taken a flyer on Thomson, and he's no longer a Senator.
Thomson was the 19th-overall pick in the 2019 draft. He played 16 NHL games in 2021-22, putting up 5 assists, and played another 2 games last season but scored zero points. He also had 72 points in 135 AHL game for the Belleville Senators, serving as arguably Belleville's most talented offensive defenceman.
On the one hand, this is a blow to Ottawa's already thin prospect depth. On the other hand, with Tyler Kleven and even Maxence Guenette looking for NHL shots this season, losing Thomson isn't an enormous loss. It remains to be seen if he remains an NHL/AHL tweener, or if he becomes an NHL defenceman in Anaheim.
