I'd f***ing love Saad on this team. Would be an ideal fit with our style, system and centers.
I'm 100% down with using Maatta, Hagelin and Sprong to try and land either Saad or Duchene.
As for the "moving Maatta makes our blueline demonstratively weaker" thing, I don't know. If Riikola comes in and continues his play from the pre-season, I think you're kinda forced to move Maatta, y'know? Brassard's gonna be tough to keep and Hags is gonna price himself outta town--even though both of those guys are as close to must-sign players as anyone can be outside of the franchise core, foundation types. Sheahan and Cullen are also likely gone. That's a significant portion of our forward corps up in the air, some of whom are extremely important (Brassard, Hags). Maatta kinda plays like he's got broken legs, and the fact that he's even able to stay in the lineup as a regular is a testament to his IQ and decision making. If we can find a similar player who can skate, even at an average level, we're infinitely better off. If Riikola's that guy, I want Olli gone asap.
