Burns has four seasons remaining on the eight-year contract he signed Nov. 22, 2016, and his production has declined since he set NHL career highs in assists (67) and points (83) in 2018-19. Last season, the 36-year-old scored 29 points (seven goals, 22 assists) and was minus-13 in 56 games. Vlasic has five seasons remaining on the eight-year contract he signed July 1, 2017. The 34-year-old scored an NHL career-low six points (one goal, five assists) in 51 games last season and averaged less than 20:00 of ice time per game (17:31) for the first time in his 15-season career. Karlsson signed an eight-year contract June 17, 2019, and like Burns, his numbers have dipped the past two seasons. The 31-year-old scored 22 points (eight goals, 14 assists) in 52 games last season, his fewest in a full NHL season.
