I mean sometimes a team claims a player and waives them a few days later and the original team and no one else claims the guy. It’s definitelty a possibility here
It's a possibility. But teams don't make waiver claims with the idea of bolstering their minor league teams. It's like NFL teams signing guys off other team's practice squads and bringing them in, only to cut them a couple days later.
The point of claiming him (which does cost $... not a lot but there is a claim fee) is to bring a guy in that maybe you were high on when he was drafted and you want to get a good look at him. You are hoping he makes the team. You aren't hoping he isn't good enough but that he will help your AHL team, because you can't count on him ever playing on your AHL team.
The post I was responding to was starting with the premise that TB was going to be filling some NHL roster spots with rookies from their AHL team, thus they claimed this guy to replace those guys in the AHL. If that was their goal there are other ways to do that.
