It depends on the magnitude of those moves. I think every single person around believes that JJ and Maatta are must-move guys, as well as Gudbranson. That's half a blueline that not only needs to be removed, but replaced with significantly better options. That alone, is an incredible undertaking that probably doesn't happen in the span of one calendar year. Then, you need to replace Phil and Horny with younger options that are better fits, particularly at ES. That, again, is a substantial undertaking.
This team can compete again with a reshuffled roster, but even if things go without a hitch, we're looking at another year or more of moves and shuffling around of pieces to get back to a strong position as a contender. That doesn't give us a lot of time to get going for another run at a Cup before Geno's out in three years, and I don't think it's realistic to see this team pull a complete about-face with regard to its approach either.
JR's got to go, and we need to initiate a rebuild, aiming to compete again in three years or so. Like others have said, it's not a rebuild starting from square one like a normal rebuild; We have Sid, who will be a significant player for us well into his mid to late 30s, we have Jake, we have Murray, we have Rust, McCann and Bjugstad. We've got pieces in place that will help us win in the foreseeable future, but we need to go through a ton of changes, whether your aim is to win before Geno's gone, or rebuild for the near future.
