Maybe an underpay, but can’t see a trade around two 1sts + Byram when you factor in the cap. I’m personally not even that high on Byram.
Girard could be sold for a 1st + at 50% retention, too.

I think Crosby is worth way more, but considering he would have all the leverage, and Colorado is pretty much the only place I could see him playing, this doesn’t seem too far off.

Guentzel is probably worth something like this… could be to any team at the deadline.
