Can't afford him.

Also he just had a similar surgery to landeskog

If the Avs could afford Hertl they'd have to consider it but they simply can't.

I won't pretend I know what I'm talking about, but Hertl's situation does seem different than Landeskog at least on the surface. Landeskog had knee surgery that was supposed to put him out for 12 weeks and it was a result of cut damage. It ended up being all season after set backs and then he had another cartilage transplant surgery that sidelined him for a second season.

Hertl in contrast was described as having loose cartilage in his knee that was causing him pain, but that playing on it would not cause additional damage (he's been playing on it all season). If the Sharks were gunning for the playoffs my guess is he would have kept playing through the pain and waited for the offseason. As it is they said he could be back after "several weeks", but I wouldn't be shocked if he took his time.

Not saying this should change your opinion on potential trades, just pointing out that I think Hertl's situation seems less dire than Landy's was.
