The fancy stats love him. He is a very good puck moving defenseman, he just is too soft to play in later playoff rounds off the bottom pair.
He can be the #5 on an excellent playoff team caliber bottom pair, Bruins are just cap broke and have too many LD. Lindholm is obviously gonna be in the lineup. And they like Forbort for the PK. That leaves Gryz, Reilly and Zboril fighting for one spot.
Problem is that any other contending team that could find him attractive for their bottom pair is as cap strapped as the Bruins.
Honestly, I’d rather try to move Craig Smith who is a pending UFA and wouldn’t cost two years of dump cost.
