Blue Jackets military veteran of the game is also Jenner's grandfather

They weren't booing, they were Boone-ing.

The Columbus Blue Jackets honored retired Marine corporal Robert A. Crompton, a Purple Heart recipient, before their game Friday against the Carolina Hurricanes.
Crompton has a special connection to the team. Forward Boone Jenner is his grandson. Fans in attendance, after a big ovation, when for the sustained "Boone" chant, usually reserved for their alternate captain.
It was the first time Crompton, who served two tours of duty in Vietnam, got to see his grandson play in person.

"It's really special ," Jenner said in a pre-game interview on NHL Network. "It's amazing seeing him get down here for a game. It's his first game he's been able to come down here so it really put a smile on my face. It's awesome to be able to play for him tonight."
The Blue Jackets presented Crompton with a camoflauge No. 38 jersey, Jenner's number, in addition to some other gear.
As for Crompton's assessment of his grandson's game?
"He's gritty. I always said Boone is like a (former Montreal Canadiens forward) Bob Gainey," Crompton said during an interview on NHL Network. "He's a grit."
