Yeah, I agree about being meh on a 3rd. A 2nd is fair, however. I think some of this thinking takes place in a vacuum. If you focus on age, you can see where he might come up with a 3rd as his value. But when you consider other variables taking place in the trade market, him being an alternative option to the more expensive guys drives his price up somewhat.
I didn't provide that link as a gotcha to say, that he's only worth a third. I think there are a lot of people here who default to "everything is worth a first (or it's not worth it)".
I don't think Anaheim benefits to wait a year for a player who's 32. The situation likely changes next year with the salary cap being on the verge of going up a decent amount. Teams will be less hesitant to overpay for rentals in that scenario. Henrique is perfectly positioned as a trade piece this year. When his deal ends, the salary cap will likely be going up (so he provides a bridge of cost certainty to teams valuing that). I can see the Avs being one of them. Last year, the Avs kept most/all of their acquisitions (I don't count Sturm since he was part of a trade requested by Jost). So I can see the Avs having interest.
