We can put the pitchforks and torches away; the riots are postponed. After losing former first-round pick Lassi Thomson on waivers, he has returned after the Ducks waived him and the Sens re-claimed him. Given that the Sens were his original team, they can place him in the AHL without fear of losing him.
Given the timing, it seems clear that Thomson was a contingency plan if Jamie Drysdale didn't re-sign before the season started. Now that Drysdale has signed a three year, $6.9M per year deal, Thomson became expendable. This significantly bolsters the AHL defence, with Thomson, Bernard-Docker, and Guenette all returning for yet another year. This also means Thomson will be waiver-exempt for 30 days or 10 games the next time he's called up.
Now we can abandon our angst over losing Thomson, and put that angst on entering the season with Rourke Chartier as the second-line centre.
