I think it's a huge positive that the whole Heinola "issue" (if there really is one, and personally I don't think the Jets see it as an issue), is that we have a good young player that at age 21 has already played multiple seasons in mens leagues with good results and is ready for the next step. We also have another young player in Samberg who is older than Heinola (and with less flexibility with the minors), that has shown he can play in the NHL. And Stanley, who has been up and down, but is also young and shown promise.
While maybe our current NHL roster of defenseman is not a collection of all-stars, they are all well established NHL players. This is not the team that had Beulieu, Sbisa, and other lower quality starters. Not outright beating one of Dillon, or Pionk, or Schmidt at age 20 and 21 is not an indictment on this young players ability or future.
Personally I think the Jets are more than fine with using the fact that Heinola does not need waivers to their advantage. It is not what Heinola would want, and I get it because he'll make 10 times more in the NHL, but it's the reality of the business. Interestingly, the Jets will still need to either trade an established D making more money next offseason, or possibly trade a young D, because we'll still be in this (not terrible) situation.
