Next year's d-core probably looks something like this:
Laurila-Emery
Strathmann-Verhoeff
MacKenzie-??
Ex. Engels, ??, ??
I think it is very likely that Wiebe and Livanavage go pro and Jubenvill transfers. That leaves you with three open spots and a particular need for righties. Other than MacKenzie, Lindberg is probably the only committed defenseman that is ready to come in and he is a righty. He's been good, but not great for Fargo this year, so I'm guessing the coaching staff would rather he be more of a 7th-8th guy for us next year. That means two more spots to be filled, one of those being a spot for a presumed starter. Neither Carels nor DuPont is going anywhere next year where they won't be dressing every night, so I'm not sure I buy the popular idea that we're going to land two of that Carels, DuPont, Lin, and Rudolph group. In a perfect world, you land DuPont to fill the right side of the 3rd pair and then a depth guy to round out the group. Although the most likely scenario is probably that we get Carels and someone plays their offhand and I'm fine with that too.
All of this is to say, I don't really think it is likely or necessary to get 2/4 from that group of elite defensemen. I'd much rather get one and save our remaining resources for an elite forward (Preston, the Rucks, etc.)
