None of this screams offensive upside to me. Like I said, it runs deeper than just the KHL this past year. I see a strong top 4D like Reinbacher. Not impossible he can't be top pairing but not probable. I would not bet money on Silayev putting up the offensive numbers to support top pairing status.
This is why we see him in some top 5 lists and not in others. Could go anywhere from 2-8 IMO.
If Silayev puts up 40-60 pts in the NHL, that means he breaks out offensively where his current resume doesn't show any signs of it. Look deeper than just the KHL.
