How in the world is bottom line minutes too much pressure? Kelly played 6:51 the other night. Mac played 9:44.
I have ZERO issue playing White for 10 minutes a game and yes I do think it would make a difference.
Kelly needs a rest, even though he doesn't play many minutes. Nowadays, it appears he is playing too many minutes, he lumbers around after a few shifts.
Maybe they are trying to protect MacArthur as well? Playing it safe with two veterans, especially Kelly who is respected by the Boston core?
Otherwise, White adds speed and spirited forechecking, and he is a skilled forward who can really give the 4th line some offence for MacArthur to work with. And I expect MacArthur to get the odd shift with the top lines as Boucher puts his lines into his blender as the game goes on.
