‘Rough ride for Ristolainen: Rasmus Ristolainen came into the 2018-19 season — his seventh in the NHL — as the No. 1 defenseman on the Sabres depth chart but has the worst plus-minus in the NHL (minus-42); Drew Doughty of the Los Angeles Kings is next at minus-30. Ristolainen is fifth on the Sabres with 39 points (five goals, 34 assists) but it’s been in his own zone where he’s struggled the most.’
