That saves Washington 3 million in cap space. Honestly Nyquist is a nice compliment player to have. He would play very well with Backstrom or Kuznetsov, but he'll disappear if he's on the 3rd line. Would throwing a Detroit 4th round pick work? or switching the 2nd round pick to a 3rd? What prospects did you have in mind?
The thing is, I think Islanders, Coyotes and Blues fans are talking about trading a decent forward prospect and a pick for Grubauer. Hurricanes fans have signed off on Orpik for Kruger, which gives the Caps 2.5M of cap space and a struggling Swede who might work well with Backstrom, or who can be moderately effective in a checking role. Does this mean the actual teams would do these things? Who knows. But in this fantasy escape world of CapFriendly, you've already been publicly outbid, maybe not in absolute value, but in marginal value to the Caps.
Your description of Nyquist is fair, and it's also my description of Burakovsky, Vrana, Wilson, Oshie, Connolly, Smith-Pelly, and (to a lesser extent) Chiasson (who had 25 points last year in a third line role and has disappeared on Washington's fourth line this year). Of those guys, Oshie got top line time last year and Wilson has it this year. The rest haven't caught a whiff, so their stats are low and their contracts are low. That allows Washington to field a really deep group of wings. They've got Walker, Gersich and Barber at the almost-ready-for-the-NHL level. And they don't have much cap space. If Nyquist were a two-way center who could counter Brassard, the Caps would throw in a 1st. But I don't think Detroit is looking to trade away any centers, and I don't think many exist who are better than Brassard in the playoffs and aren't already in Pittsburgh.
Orpik is old and slow and expensive, but he contributes something no other Cap brings: four hits per game in the playoffs, average, career, and pretty much every year. Over a seven game series, that can build a lot of momentum. Nyquist is equally expensive, and brings something the Caps have in spades. He might be the best and most established player in the trade, but in Washington he'd be a slight upgrade over Burakovsky, keeping Burakovsky toiling in obscurity in the bottom six. Since Bura is a recent Caps first round pick, and since he got fifteen goals last year and is a healthy scratch a fair amount this year.... I just don't see the Caps wanting an older, more expensive replacement.
The reason the Caps consider trading Grubauer at all is fear of losing him to an expansion team. So ideally they'd trade him to a team with no goalies whose contracts have positive value, and get back future potential.
Trading Orpik for ericsson is tempting becauase Ericsson has good corsi relative to zone starts and a lower cap hit, but it means the Caps give up Orpik's toughness and physical presence in the playoffs, which are pretty well unmatched. Again, they'd consider it in order to re-sign Carlson and have enough cap space.
Trading Grubauer for Nyquist isn't ideal. It probably raises their cap number (although who knows how much Grubauer gets as an RFA this summer) and adds to another position of strength. If you could teach Nyquist to play center or right defense, I'd be all about him.
