San Jose Sharks are in the thick of a playoff race, where mistakes are magnified. Rookie defenseman Sam Dickinson had a moment to forget during a 6-3 loss to the Buffalo Sabres, where he was pressured by Sabres forward Beck Malenstyn. This incident was part of a growing trend for the Sharks, who have lost their third consecutive game to the Sabres. Coach Ryan Warsofsky acknowledged that some younger players are learning on the fly in a pressure-filled environment. Dickinson, who has played in 26 of the Sharks' last 27 games, has 10 points and averaged just over 16 minutes in ice time in 52 games this season.
