not for nothing but erik gudbranson is fourth in ATOI on the team. obviously F/D comparisons are flawed here but he has higher ATOI than jenner, too. even if he's nominally on the third pair moving forward, he'll be surrounded by enough young guys that he'll likely still play significant minutes solely because of PK duties.
and, again, florida had a fourth liner (derek mackenzie) as the stopgap from willie mitchell to sasha barkov. and i mentioned okposo, who is buffalo's captain and gets revered in the same way jenner does, while being a fourth liner.
i get that it hurts to move guys like boone, but sometimes it's necessary. it happened with foligno, it happened with jones, and it happened with cam atkinson. it's never a "we need less of what they're bringing" thing, it's a "this is the right decision for the franchise."
if you can get a significant package of future assets for a soon-to-be 31-year-old with a career high of 49 points and a bad back, you can live with a stopgap leadership solution, especially when you have a guy like fantilli who has NHL captain written all over him.
