In the same vein: I've said it before, but if there's another team, like us, who has a 4th defenceman that is a threat to be taken in the expansion draft, and due to this are offering him on like a "25% discount" (ie: we want to get 75% of this player's value in a trade rather than lose him for nothing), then I'm buying.
Trade for that defenceman, then leave both him AND Methot exposed in the expansion draft.
If we lose Methot, then we effectively traded for a replacement defenceman a few months early (rather than wait until after the expansion draft when prices might be higher). If Vegas takes "new defenceman" that we got in the trade, then we still have Methot, and the blueline just keeps trucking on like nothing happened.
The key to this strategy is to not get someone significantly better than Methot. We don't want to over-pay by acquiring a guy worth significantly more than Methot who we would lose.
Heck, I'd be very willing to offer one of Quincey or Russell 2/3-year contracts (assuming they're not still asking the moon, salary-wise) just so we have other defenceman to dangle to Vegas and/or have as backup in case we lose Methot. Heck, maybe Russell has a rebound year for us, and Vegas likes him more in the expansion draft? I mean, that's a best-case scenario for us right there.
