One one hand, based on stats/metrics/whatever (because I haven't watched him play), Garland basically seems like a middle-six, five-on-five replacement/upgrade for Sheary. (But IIRC doesn't kill penalties and would get minimal PP time.) And if VAN was willing to retain 30% (as
tweeted by Kevin Weekes) those extra two years on Garland are much more palatable.
On the other hand, with Mantha scratched, our current middle-six wingers are Oshie, McMichael, Milano, and Phillips. You trade for Garland, you've got to play him, so who of those four would you immediately bench/demote/trade to make room for Garland? (Please, I don't want to hear any Oshie-to-Seattle nonsense.) And, as easy as it is to forget about Pacioretty, we've got to remember that he's supposedly coming back at some point and could possibly even stay healthy, so then there's another surplus middle-six winger situation you've got to deal with this year. And that's not even including the Miro situation.
IDK. I want to get rid of Mantha as much as the next person, hopefully without 1) paying a premium to dump him or 2) taking on a contract that restricts the team's roster flexibility later on. But--unless there's an equal one-for-one trade involving two troubled assets/contracts that need a change of scenery--one/both of those things feel like they'd be necessary. In which case the best option to me seems to be for the team to hold its nose and swallow the contract for this last year. Bench/demote his ass until someone gets hurt or their game goes to hell, then put him in and see if he can play well enough to either 1) contribute to a possible wildcard playoff run, or, 2) if the Caps are out of the playoffs race early, return a draft pick in a deadline trade.
