They do. Career minor leaguers almost never file. I honestly can't recall a time a guy like Lipon has filed, they would likely get less than their QO. It's just not a thing they do.
Only one I am surprised filed is Dano. Means he is interested (for some reason) in continuing to play with the Jets. I'm guessing he is counting on his strong advanced stats to get too much for the Jets liking and forcing a move out of town. Which wouldn't be hard, anything awarded over a million and I think they move him. He needs a place where he could get into the top 9 to showcase his offense. He still has 40-50 point upside.
I'm honestly not too surprised.
He has a good relationship with management despite not playing it seems, as well as the players. On social media he's posted stuff often of him supporting the Jets when he's not playing.
Not to mention not only one, but possibly 2 RW positions have opened up. Armia, obviously, but the loss of Stastny means Roslovic very well could get a good long look at center, so plenty of space has opened up behind Wheeler and Laine/Ehlers.
Despite his questionable decision making at times, PoMo isnt stupid. He knows what Dano can bring, but it just didn't seem to fit what he wanted on the 4th line (matchup line) and Roslo had him beat at the 3RW spot, deservedly so.
Barring any trades, I think one of Petan or Dano will be playing with the Jets full time next season.
