If there is ever a team that is in need of a Kreider and will have money to spend next season and years to come, it's the Buffalo Sabres. About half their team is expiring deals. They have some very finesse forwards either in the system or on the team. He can keep up with Eichel and provide the net front on PP1.
They also need to make moves to win now. Eichel won't want to stick around if they keep floundering. It'll be up to Kreider if he wants to go there. I'm sure if he's close enough with a guy like Vesey, who may or may not be there, but is also a kid from Massachusetts, he could get an idea of what being in that city is like
Also, would he believe that they are going to be winning soon. I'm sure being here the past few seasons hurts due to losing. He's going to want to have a shot to win and be paid.
