If we're doing a retool this season...
Montoya (when he's healthy) for Kari Lehtonen, Remi Elie, and a 2nd round pick. Dallas gets a better backup now and next season, but pays a price for getting significant cap relief for trade deadline acquisitions.
Plekanec (at 50% retained salary) to Winnipeg for a 2nd round pick. They look like a team that could use a defensive 3rd line center... also Pleks is prepared for Winnipeg winters with his collection of turtlenecks.
Then whatever assortment of 6th and 7th round picks you can get for Davidson, Mitchell, and Hemsky.
I'd also loan Mete to the World Juniors in December, then send him back down to his junior team right after. No need to taint the kid further with this mentally fragile locker room.
Call up Jerabek, but look to flip him at the deadline for whatever value he performs to.
Finally, not sure what the value is on Pacioretty, but if you want to get a message across to the team that the locker room atmosphere needs a change, you deal the captain. I'd look to San Jose, L.A, Nashville, and Dallas (hey, check out all that cap space!) for the best offers. Maybe Carolina as well.
