Nathan Lieuwen

Lieuwen, a former sixth-round pick, took a step backwards in his development last year, serving as the backup in AHL Rochester after appearing in seven games with the Sabres the previous season. He won just four times in 16 appearances and posted an atrocious 3.29 GAA and a poor .883 save percentage before he was shut down for much of the season due to a concussion. As an impending free agent, Lieuwen should be motivated heading into the upcoming campaign, but he'll face stiff competition from Rochester's two other goalies and could end up as either a backup goalie or even get assignment to the ECHL.
