no but there is such a thing as mutual termination
if the player agrees to it they can do it.
in this case I can't see the player wanting to be back in Vegas
There may be mutual termination but it doesn’t mean that the player could declare himself a UFA in the middle of the season and sign a new contract in a new town so that he can play the rest of the season. Or that the team would get any cap relief.
Fans make a big deal about issues like this but most players know it’s a business and try not to get caught up in getting revenge against the club. They want to play for their teammates and they want to be positive and effective so that they can be viewed as a good asset and move on to a good team. At this point, Dadanov doesn’t have much value, but if he somehow managed to help get the Knights into the playoffs, there would be a lot more teams interested in taking him on.
The real issue is whether the VGK need his cap space to bring in someone who could help them out in the short term to get into the playoffs. I would suspect that getting rid of his cap hit was primarily to bring Martinez off of LTIR to help shore up the defense. Having Dadanov take up a roster space when they are bleeding goals doesn’t help them in the playoff hunt.
