Kennedy had 1 goal and 2 points in 27 games for the Panthers this season. The 25-year-old has 11 goals and 29 points in 112 career games for the Sabres and Panthers.
Sullivan, 27, was playing at Worcester in the AHL this season, where he had 5 goals and 24 points in 32 games. He finished with 12 goals in each of his last two minor-league seasons, for Worcester and San Antonio.
He's, believe it or not, actually one of my favorite guys, and I've ended up trading him twice. I appreciate what he's done. He was one year away from being an unrestricted free agent, and I felt with this opportunity, that it was a chance that we were able to get somebody for him in Nick Bonino and Adam Clendening.
