I love Markov, but his impact last season has become mythological. His age was definitely starting to show, he was looking old and weak defensively. He always was a bit but smart positioning and stick checking made up for it, but decline from age was showing. The Rangers were targeting him hard in the playoffs with soft dump ins to his corner, and he was struggling. Weber basically was carrying, which Weber can do with almost anyone, but that's not exactly ideal and not worth the kind of money Markov wanted. Markov would have really looked bad this season with Weber out injured.
Radulov loss was tougher because he is a prime age impact player , and that represents the missing 8$ million talent in free cap, but I don't know if him alone would have done it. This D looks so bad right now without Weber and Price is having a difficult season. Would Radulov make up the -29 differential and near bottom in GA? Don't think so.
