How do the points work? Is this H2H, or are there "active" slots where you can keep accruing points while Montour's on the waiver wire and not costing you?
I'd be looking for any excuse to keep him at that price point. Even if he misses half the season, he'd still be a bargain the following year.
JEE seems pretty locked in with Boldy and on the Wild's PP1 since he is the only real strong FOW guy they have with offensive touch. I think he's a solid bet for 55 points, with a little upside. If that's worth 4% of your budget then he's a keeper.
Tavares probably costs about the same if you try to re-buy him. If he has wing eligibility I keep him at that price.
