Show me a comparable for Lindgren getting a first in the past. 30 year old goaltenders with 84 career games played and 0 playoff appearances don't command 1st round picks at the deadline.
Fleury only got a 2nd (conditional up to a first if Minneosta reached WCF, condition not met) when he was traded at the 2022 deadline, and he's a heck of a lot more established than Lindgren.
Robin Lehner, also considerably more established than Lindgren, got a 2nd and Malcolm Subban (who Vegas had acquired via waivers) and a D prospect that has never played above the ECHL.
A 28 year-old Jack Campbell (50 career starts) was traded (along with Kyle Clifford) for Trevor Moore and 2x 3rd round picks.
Best case comparable is something like Darcy Kuemper's trade from LA to Arizona, for Tobias Rieder (a mid-20s 3rd liner coming off a couple decent seasons) and Scott Wedgewood (then 25). But Kuemper was 27, not 30, at the time of that trade.
Dowd is only getting a 1st if we retain on him. That's already an ambitious ask. 4th line centers don't often command a 1st round pick (last one was Paul Gaustad a decade ago). The reason why Dowd can fetch a 1st is because he has a year remaining on his contract, and retention can bring his salary cap under league minimum next year, making him an incredibly efficient salary slot to a cap crunched contender. His trade value actually goes down if they hold onto him until next season.
