Ceulemans' upside is more on the offensive end. He seems like he could be another Faulk. But Faulk has taken a lot of strides defensively since he arrived, and he arrived as a veteran already. Ceulemans is going to take time defensively, but will have that offensive skill. I think if we think Parayko is going to stay, RD is less of an issue. One of the reasons I favor Lambos is because projecting forward, Scandella isn't the guy we wanted him to be, Dunn seems like he'll either be traded or ED'd, and Peru is a PMD in the vein of Dunn. There's an easier path to top 4 on the left side than the right, barring Parayko leaving. Lambos is more what we lack in a stay-at-home defenseman where as Ceulemans' strong suit is what Parayko, Faulk, Krug, Peru, and Dunn (again, who knows if he'll be here) all bring. If we needed a PMD, then the scales would tip to Ceulemans. As is, I think the hole is bigger on LD a year or two from now when these guys would be coming into the picture. And the hole in defensive defensemen is bigger. Mikkola is a nice player, but I'm not sure many are safe projecting him to top 4.
