It's a shame you didn't watch the game.What are these in-game adjustments you speak of. All he did was realize his new lines are getting stomped, so went back to the old ones.......
Early on, Keefe double-shifted Matthews between Kerfoot and Nylander instead of Kampf on O- zone faceoffs, for example, long before he put the old lines back together.
If you had paid attention you would have seen several instances throughout the game where it wasn't just the same-old, same-old.
I can think of some other coaches who would never change a game plan, no matter how badly it was working. That's probably why Keefe has one of the best winning percentages in franchise history.
