Avs traded from a position of strength for one of need. I'm not sure what Buffalo was looking for. Value? They got the more dynamic guy with a higher potential ceiling, albeit along with some risk, but it's not as if they were starved for a young stud defenseman.
We'll see how it shakes out.
I think that was exactly what they were looking for.
Adams has regularly targeted all the guys the front office identified as core, and started negotiations with them all not long after they were extension eligible. Adams never even once called Mittelstadt's agent, even though Casey had been extension eligible for quite a while and his contract was rapidly expiring.
For whatever reason, they did not see Mittelstadt in the teams future, even though he was the teams leading scorer. A puck moving LHD was one of the last things the Sabres needed, but after the trade, they went with a sales pitch of how Byram was a player they had been looking at for a long time and were targeting, which makes zero sense with Dahlin and Power already in the mix.
I am pretty sure that Byram was just the most valuable piece they were offered for Mitts and they did not want to negotiate with Casey (who was arbitration eligible and likely would have demanded a deal similar to Thompson or Cozens in the 7m+ x 7 range had he stayed in Buffalo.
