If Chevy had any intention of getting a Dougie Hamilton type return he could and would have traded him several times. Obviously, Chevy won't accept that return and doesn't have to because he has no fear of an offer sheet, unlike the Bruins when they traded Hamilton. In fact, the Jets would probably welcome an offer sheet because they could simply match and Trouba would be tied to them with his only recourse being to sit out with no pay cheque.
A Dougie Hamilton return is all Trouba is worth and it's stilly to think otherwise.
A lot of people look at the Hall Larsson trade and think Trouba is worth more than Larsson because he has more upside (which he probably does), but they fail to realize that Trouba isn't as proven a Dman as Larsson, and is looking for a big contract. Larsson was signed to a really friendly 4.25m/year cap hit.
Trouba on the other hand is in a similar situation to Dougie, with no contract in place and expecting a big raise. Dougie was more proven than Trouba when traded (more than Larsson as well), and has more upside than both.
Jets fans who think Trouba can fetch a return like Hall are delusional. 1- Larsson was a much better trade chip than Trouba and 2- There's only one Chia. No other GM will make such a stupid trade.
