The Sabres previously acquired Vesey's draft rights in June 2016, when he was months away from unrestricted free agency after completing his senior season at Harvard. Though his discussions with Buffalo were positive, he opted to explore free agency and ultimately signed with New York.
"I think the whole time, I had nothing but positive things to say about the organization and the pitch they made to me," he said. "But at that point three years ago, I had kind of made up my mind that I was going to go to free agency and that's what I did.
"At that point, I thought New York was the best fit for me. It's crazy how much things can change in three years, but … I'm pumped to be on the team. Now I've got some familiarity with some of those guys, so I think it's going to be great."
Coincidentally, Vesey's familiarity with the Sabres extends to three of their centers. He trains with Jack Eichel during the summer and knows Evan Rodrigues from their mutual friends in Boston. He's even gotten to know Casey Mittelstadt over the years.
"I think the thing that's attractive about Buffalo just looking at the roster is they're really building a strong group of centers and highly-skilled guys," he said.
"For me, as a finisher, I think a center that's going to possess the puck and distribute it, I think that's attractive to me. If I'm able to hook up and get some chemistry with some of those guys it will make me better."
Vesey, a left shot, joins a mix of wingers that includes Jeff Skinner, Conor Sheary and Scott Wilson on the left; Sam Reinhart and Kyle Okposo on the right; and Alex Nylander, C.J Smith, Tage Thompson, and Victor Olofsson all aiming to push for NHL roster spots this fall.
That's a lot of competition, which is exactly how the Sabres want it.
"What we like with the trade is it just gives (coach) Ralph (Krueger) some more options," Botterill said. "We're excited about some of our young wingers that we have in the organization.
"I think the fact that a player such as Conor Sheary can play both wings, a player such as Alex Nylander has played both wings, here's just another player in Jimmy who comes into our organization, can help us with even-strength scoring and just give us different options throughout the lineup."
