Even without the NMC and recapture issues, not sure anyone would want to sign up for the 2nd half of that contract.
But, for ***** and giggles. Something around Krejci? Same age, #1C vs #1D, similar cap hit. Suter is probably a SMIDGE more valuable right now, but those extra years on the deal until he is 40 negate any extra value there.
I would think the recapture issue is Minnesota's problem. If they want to trade Suter for some reason, I don't think that's a deal breaker, and it shouldn't affect what return they get. Nashville traded Weber, and that pretty much dispels the idea that recapture is a huge deal.
As for the contract, I see no issue there either. First off, it's a front loaded deal. It's a salary saver and that has appeal for teams, and makes him a tradeable asset to a team getting to the cap floor late in the deal.
Also, he's a very steady Dman with elite skills, and those types tend to last very long. Many Dmen like him make it to 38-40 years old, and some play even past 40. He doesn't play a style that wears down very quickly, and hasn't had much injury issue.
A 7.5 cap hit for a top D is very cheap, and as the years go by it becomes a lower and lower percentage of the cap. In the final years of the deal, there's a good chance he would not even be overpaid.
Suter has a ton of value, and in a trade I'd expect nothing less than a 1 for 1 trade for another elite player. If it's for smaller pieces, they would get a huge haul I'm sure.
