Hall is meshing well with Krejci and Smith
In his last post game interview, the coach wanted a big bodied third line, hence Kuraly moving up to center Ritchie and Coyle.
Bruce says each line has to have an identity. Two skilled lines that can score followed by a grinding, large line, and a 4th line that can bring speed and energy.
Judging by how the lineup is set, Jake needs to play with pace and tenacity, which use to be hallmarks of his game. Another first round pick, Curtis Lazar, centers that line and while he may not score like a 1st round pick, he works hard and makes himself useful. I think DeBrusk can help that 4th line produce some points with his level of talent, but if he's not working hard and bringing his skating game, he sits.
Im not a huge Kulhman guy, but he gets coach praise because he always keeps his motor running hot. Hopefully, he and Lazar rub off on DeBrusk and he finds his skating game again. He shows it in flashes, but consistency is lacking.
It's also way too soon to give up on him. A Hall injury and/or Ritchie spending 6 nights a week at Five Guys again will leave an opening for someone to step up.
