I wouldn’t make any of those deals. I see zero reason to gut the youngsters to sign good players to exorbitant contracts. I’d keep Jokiharju and 28 over a rental of Dumba seeing as he’d likely look for a 7mil deal in the off-season which won’t fit well with Dahlin and Power’s eventual mega contracts. I don’t want 3 Dman making 21+ mil as we’d fall into SJS’s trap essentially.
Fiala wants way to much to be a good target. He’s a winger and more or less a 2nd liner on a great team; they don’t make 8.5mil
I wouldn't do the Fiala deal either, I'm just giving an example of what they would want.
Given our likely forward make up (no elite center/wingers, running something like 3 2nd lines, essentially), we could easily overpay our top 3 defense. In fact, having an elite defense is probably the only road back to consistent contention as we don't have a path to get an elite center other than by blind lotto luck or having someone fall to us in the 10-20 range that develops into one.
But, overall, assuming a d-man, even one as good as power, is going to need a mega contract in year 4 when we've only see a handful of games is foolish. D-men take longer for their game to develop. The ideal is bridge -> mega contract. I think they've learned their lesson from ownership about going to that huge deal right away.
