Look, goalies in general, no matter what their name might be, aren't worth much anymore. The way the game is played today makes goalie-centric team-building obsolete. Every year there's an average goalie who got hot at the right time hoisting the Cup. You don't need Hall of Fame caliber goaltending to win anymore. If Patrick Roy and Marty Brodeur were both in their prime today they would be nothing but salary cap anchors for their teams. They would be the reason why their teams couldn't afford to load up on the players you need to win Cups.
The Habs could put Price on the trading block today and offer to absorb 100% of his salary and they still wouldn't get great offers for him. Even a decade ago you could have got a king's ransom for a top flight goalie. Today? Not so much.
As an example, I recently tried to shift some antique furniture, a mid-1930's art-deco style bedroom suite. The dealers I spoke with all agreed it was good quality, well made furniture but they also told me that it's essentially worthless because it's not a style that is popular right now. Quality doesn't matter if there's no one willing to buy it. Right now, the hot seller in the antique market is Scandinavian style, mid century stuff from the 50's. That's what sells. Is it as well made as my 1930's pieces? Probably not but that doesn't matter. What matters is what people are willing to spend money on.
Goalies right now are no different. Nobody builds a winning team around their goalie anymore. You want a good one, not an overpriced great one who will eat up too much of your cap. They don't need to singlehandedly win games for you like Roy and Brodeur used to do. They only need to not lose games for you.
So no, sorry, but Charlie Lindgren is a useless asset as far as trades go. He has zero value around the league and is only worth something (just barely) to the team which currently employs him. It's not that other teams wouldn't take him as a throw-in, just that they aren't going to pay any sort of premium for him. Adding him to a trade proposal does nothing to bump up the value of that proposal. He's a non-factor. When you trade a goalie today his last name may as well be "Future Considerations" because that's about all he's worth.
If Pacioretty alone won't get you the 10th pick from the Oilers or Borgstrom from the Panthers, Pacioretty and Lindgren won't get it for you either.
