Granato and Adams expressed excitement about the continuity on the roster, with 11 of the Sabres' 13 leading scorers under contract for next season.
The Sabres have six restricted free agents: Victor Olofsson, Jacob Bryson, Arttu Ruotsalainen, Brandon Biro, Brett Murray, and Ukko-Pekka Luukkonen. The Sabres can extend qualifying offers to each of these players, which would give them the opportunity to match any offer from an opposing team.
Buffalo's list of unrestricted free agents includes forwards Drake Caggiula, Cody Eakin, Vinnie Hinostroza and John Hayden; defensemen Colin Miller, Will Butcher and Mark Pysyk; and goaltenders Craig Anderson, Dustin Tokarski and Malcolm Subban.
That leaves goaltender as one position of interest heading into the summer. Luukkonen is 23 and could take the next step after posting a .917 save percentage in nine games with Buffalo this season.
Anderson, 40, said this season was among the most fun of his career but added that he will take time with his family before making a decision on his playing future.
The Sabres also have long-term prospects in Devon Levi and Erik Portillo, both of whom are returning to the NCAA next season.
"Big picture, we feel good internally," Adams said. "We'll look at different options, but what we won't do is do something to box ourselves out that maybe we would be uncomfortable down the road."
Adams said he will take the same approach when it comes to improving the roster outside the crease - staying respectful to the process that began this season.
"You can't hit fast forward," Adams said. "You can't say we're going from here to here. It's a process. This is about us getting better. We're not satisfied right now. We played some really good hockey at the end of the year.
"I liked the growth of our team, I liked the growth of some individuals, the majority of the individuals and the way it came together. But we've got a long way to go, and we've got a lot of work ahead of us. We want to make sure we're setting this organization up for sustainable long-term success."
