But you are saying he won't do that until the Sabres are a good team. If Kevyn (and the scouting staff) knows enough about Robertson to think he could be part of the core, and the opportunity to snag him comes up, why wouldn't he go for it?
We've seen Kevyn stick to his plan so far, but who's to say bringing in young top players for future assets isn't in his plan? It could simply be a case of the right deal hasn't come up yet. And maybe this isn't the right deal either, in terms of the return Dallas is looking for. But if Dallas is cap strapped, maybe their ask will come down as we get closer to the season start. The question in my mind is what Robertson is looking for in salary and term. I'm sure Dallas knows what his ask is, and would probably tell Kevyn what their offer was if they thought it could facilitate a trade.
