Means nothing for how good of a player he is, especially today when he won a cup years ago.
Like I said, he's young and has played a lot in the NHL as a young player. That doesn't mean his performance has been good. Jack Johnson played a ton as a young NHLer and his results were also similarly shitty.
If you have to cling to "toolbox" and "intangibles" to say his performance in the NHL has been good, that just says his performance in the NHL hasn't been good.
From Sabres fans from a thread I found:
I've been sitting on some of this for a few days but here is part 1.
On Defense:
Marty Wilford: F as in f*** Off. Please take him and his oversized chin and fire them into the sun. No one he has worked with has markedly improved their game. I would assert that several key members of the unit have regressed season on season with him as their coach in Power and Samuelsson. The only player who has seemed to grow was Dahlin – the guy who was marked to be the next great defenseman, 1OA, who still has things in his game that need to be better. He cannot, must not return in any capacity and...
I'm not going to act like Byram is terrible, he clearly has tools and there is definitely upside there.
