Sabres beat writer for The Athletic has said he was 99% sure the NMC clause was gone with trade.
What a lazy beat writer. Is it that hard to talk to Botterill to confirm? My understanding about NMC/NTC clauses for guys who are into their UFA ages, is that anyone with one, it does NOT automatically continue on with you if you get traded, unless the acquiring team signs an amendment to acknowledge that they will honour it. For a player who has such a clause, I would bet that they would insist that the acquiring team honour the clause otherwise he won't waive his NTC/NMC to go to that team. Thus, the vast majority of guys with such clauses keep them onto their new team. See, Phaneuf, Kessel, etc. The guys running cap friendly have him listed with a NMC.
Only the RFA guys like Subban, if they get dealt before the clause kicks in, can the acquiring team opt not to honour it, which the Preds choose not to.
Who knows what Skinner will or will not do.
Pros of waiving - get playoff experience. Possibly improve your stock
Cons of waiving - have a poor playoff or get hurt when the intensity picks up, thus damaging what you can get in the new contract.
