Regarding the center prospects, yea its a problem. But right now we have NHL centermen. We don't have a single right shooting offensive defenceman, a fact that Babcock has bemoaned for years. We do have an overabundance of dman prospects that look like they will for sure be NHL players someday, but not right now. We will have to trade at least one of them in the next two years or so because there simply isn't enough roster space for all of them. Why don't we trade our highly promising center prospect to address an urgent need now, and then use our highly promising defenceman prospects to address a POTENTIAL need later?
From my perspective, I don't see Myers putting Detroit over the top in the next two years - maybe that's just me. Around that time, Sproul and Jensen should be on this team. I'm not sure the ceiling between Sproul and Myers is that far apart.
I agree that this team is going to have too many NHL caliber defenders (hopefully), and I think one or more should be packaged, but with a winger - not a center. Again, in terms of relative value, I feel as if Larkin is worth more to this team. I don't think you move two of Ouellet, Sproul, Backman, Marchenko and/or Jensen and get someone like Larkin back.
IMO, it would be poor asset management if Holland moved Larkin today, hoping that he can move one or more of those guys down the road for another center. Perhaps if this team was in a better position to win a cup, and Myers was a for-sure impact defender, I'd make the move. At this point, I think Larkin's perceived value to this team is greater than Myers' immediate value. Just my take on it.
