These reports are only mentioning the new teams that he's met with. The Sabres are the only team that Vesey's team has talked to on multiple occasions, so I wouldn't say that the Sabres are barely a blip. TSN even reported that he and the Sabres were in "negotiations" right up until the night before the deadline, and not just giving a sales pitch.
I think they'll be in the top 3. My completely uninformed guess is that he stays home with the Bruins. But I wouldn't be shocked if he chose to play with Eichel either. Regardless, I don't feel like this is a franchise changing decision that teams are waiting on. It's just a rare chance for a team to get a cheap, young prospect that could develop into a solid pro. He will never live up to this hype, unfortunately.
