Riiiiiight.
Nobody is saying the sabres have to trade ROR. But as much as the Blues need a top 6 center, I think it's fair to say that the sabres need a culture change at least as badly (if not more).
So if you want to threaten to take your ball and go home, like a mature adult (lol), then it's also fair to point out that there are more potential top 6 center options for the Blues to pursue than there are sabres players they can move to change the team culture. The Blues can pursue UFA's like Tavares, Stastny, Bozak, or try to trade for another C like Johnson, Brassard, etc.
How many players do you think there are on the sabres that are part of the team leadership who they could realistically trade to improve the team culture/locker room? Moving a bottom 6 winger or 4/5 D probably isn't going to impact the team culture much IMO. I don't think it would be a good idea to bring a young kid like Dahlin into that locker room unless there are significant changes from the end of last season. But hey, at least season ticket prices aren't going up next year...
...OR, instead of all the B.S. bargaining tactics above ^^^ we could actually try to think of a reasonable deal that could benefit both teams. Seems like a better idea to me. What are Buffalo's needs? Wingers, defense? Blues have several very good wingers, picks, and pieces other than Parayko.
What about something around ROR for Dunn + good winger prospect + pick + roster player?
