It is quite a possibility. The Kings were looking for a veteran depth defenseman... I wouldn't be entirely surprised to hear them putting in a claim when all is said and done.
"It has not been a good day. I lost my glasses early this morning and I had to go buy a pair of 79 dollar reading glasses today. 79 bucks. You can literally get them at Costco, three-for-20." - Darryl Sutter's response to going up 2-0 in the series.
Personally I don't see why a team wouldn't claim him other than to avoid messing with Chicago. Cheap and can be an effective depth defenceman... you never know when someone is going to go down in the playoffs or in the remaining regular season.
You're right, if a team claims him they can't play him at all. I found this from 2 years ago involving Toby Petersen.
The process involving re-entry waivers changes after the trade deadline, as a team can claim Petersen for half price and place him on their NHL roster, but they cannot play him in the regular season or in playoff games for the remainder of the season. That allows teams to make call-ups like this without much risk of losing a player.
Strange, but I guess it could still make sense for a team that needs organizational depth. Call up a kid to play in the NHL, and Boynton taking his spot..
Mike Heika of the Dallas Morning News did some research on the topic & found that players claimed on waivers after the trade deadline can't play in the regular season either. Not the 1st time I've heard this.
Ducks waived him and no one wanted him, I don't really see anyone wanting him now either. Most teams didn't make big moves to save cap space or because they didn't have any space.
The interesting thing is now it is past the deadline. If you really want or need a 6th D-Man you can pick one up. There are now no other options. I doubt anyone picks him up to be a jerk. But maybe someone with a chance for the playoffs has a need and will pick up a veteran 6th D-Man.
