I don't see it that way Stoner. The analytics say we have ONE very good defenseman (Dahlin) who carries whoever he plays with.
If a team has only one good defenseman they will lose a lot of games, which the Sabres do.
I did some quick research, Dahlin was out injured for a large part of the 13 game season killing losing streak. He was gone for all the games between Dec 3 and Dec 20, and he was playing hurt prior to that. When he came back he had 4 assists and we finally won a game.
Take away that miserable 13 game streak, just play .500 in that space, and the team is playing at a wildcard spot right now.
The analytics say they if you trade Dahlin and don't replace him with a better defenseman, your team will get worse. Chances of a real NHL team trading away a defenseman better than Dahlin is ZERO.
The analytics and the losing streak tell me that Power and Byram did not step up.
Should one of them be traded? Yes, but only if the GM can make the NHL Team better right now. No more trading for futures, get better NHL players using one or more of them in trade.
Which takes us to the real problem, a problem created by Pegula and his band of bad GMs. Which is, who will come here?
