Habs really only have 22 roster players signed, including Moen and 2 goalies, and tons of extra cap space, so there is really no reason whatsoever to do anything with Moen right now. He starts the season as a 4th or 5th liner for us, no harm whatsoever. If he's ever going to have any market value, it will be later in the season, not sooner.
The Habs think Tokarski is better than Budaj, based on the playoffs. They probably hoped they could deal Budaj in the summer, but that ship seems to have sailed as all teams have their goaltending set up now. You just ride that one out. Set up a battle in training camp. Waive somebody (almost certainly Budaj) on October 1st if no trade market has materialized. No biggie. If there's no trade market, it's also unlikely there'd be a waiver claim.
