Bruce made a lot of adjustments. He made a goalie change. He benched flash in game 7. He gave Tyler Sloan an opportunity. He made a ridiculous amount of changes in the PP.
No changes to the system itself. Changing players means absolutely nothing if the other team knows what they are going to do no matter who is on the f'n ice. How about a simple adjustment like putting two guys in front of the net instead of one on the PP? Not a single change in gameplan. No line matching. Nothing.
