I would do a significant package for Crouse. Kings have the cap space for this season to make the deal without sending cap back...I'm pretty sure anyways. If you need to move a similar contract like Iafallo later on, do it then even if it means less value in an Iafallo trade.
If Blake isn't all-in right now, he's at that point when you walk into a cold pool instead of diving in and your about to have your balls enter the water. Crouse is the type of player the Kings have nothing like on the big club, on the farm or with any future f***ing pick because he isn't a average sized center or RHD.
Want to talk identity and all that? The current identity is "please give us power plays and please don't start being mean to us". This team needs a guy like Crouse in a bad, bad way. I'd argue more so than Chychrun regardless of the hole at LHD.
