Finnish article interviewing Mikko Rantenan
He gets asked about who the hardest defenseman in the league to play against are, here's a part of the article:
"Colorado Avalanche's superstar Mikko Rantanen answers the question of who he thinks are the most difficult players to play against.
'Boston's d-pair Charlie McAvoy and Hampus Lindholm come to mind immediately. Especially when we're playing against them in Boston and they have the last change. Haven't been able to do pretty much anything against them in a couple of years.', the forward tells Iltalehti."
I think an underrated part of potentially trading for Hanifin is that he is capable of playing those tough shutdown minutes that come with playing with Carlo, so you could run Lindholm-McAvoy as the top pair more frequently. Those two dominate every time they play together, and especially with no Bergy to throw at top lines, having those two together could have a similar effect.
