it's probably not the worst in terms of value. But, Risto is already 3 years into his development, and I see him as the best player and most valuable piece in this trade, so I don't know if Buffalo is looking to start over with another Finish dman. It comes down to how good you believe Tanev is. Some people are really high on him, other's not quite as high. No doubt, he's a quality D, not sure what his ceiling is. If these teams were in opposite positions, where Buffalo was looking to rebuild and Vancouver was looking to take that next step, it would make more sense, but with things as they are, I don't see Buffalo moving their best dman.
