When the Sabres were trying to move O'Reilly, those talks were about how they were not willing to take anything less than an overpay. It seems like the organization hasn't learned from their past now with Eichel.
Of course you cannot give him away for nothing, but looking to get guys that were just drafted in the top 5, some not even in the NHL just yet, is just not something that happens. They aren't going to be able to get a Byfield type player from the Kings. Someone like Fox isn't going to be in that deal.
People bring up the Matt Duchene trade, but that was just a really bad move by Ottawa and Nashville where Colorado took advantage of both organizations. Buffalo should be trying to get 5 pieces, with two of those being high end pieces, another two that are good pieces, and a draft pick.
Some people might not like it, but the Rangers package would be something like this in that mold: 2021 1st, Chytil, Lundkvist, Gauthier, and one of Robertson/Jones.
