Your projections are very optimistic. I could say, for my team, that Ek, Kaprizov, Greenway, Sokolov, and Kunin are all going to be on the top 6 in three years time, but the reality is that Kunin's knee got blown out, Greenway has played a handful of games in the NHL, and looked just ok, KK might never come over to the NHL, Ek looks legit, but might never be more than a good #3C, and Sokolov might never make it out of the AHL.
You only have to look at how Grigorenko and Larsson have turned out to temper your expectations.
Bottom line is that CM is probably going to be out on a line with little or no proven talent for this year. If nothing else, they need to make sure that he has a physical presence with him to watch his back, which you should do with any talented rookie.
BUF needs to pray that they can get a couple of decent years out of KO, and that Dahlin is all that, because the forward talent has take a hit. I do have some hope for Thompson...he has some skill. Just don't know if he can make it happen in the NHL.
