My first memory of Rolston was the 2009 World Juniors, Team USA built a 3-0 lead on the Canadians and then they simply fell apart. He had no system or direction, and when the game started to turn he let his emotions run, leading to his players losing their composure too. I remember holding him solely responsible for that loss.
You could argue he shouldn't have even been the Amerks coach, poor player development or even steps backward by key prospects under his tutelage as well as being wildly outshot with no recognizable system. Probably belongs back in the college ranks to start over and learn his way back to a higher level. However, I highly doubt hell have the makeup to ever be an NHL head coach again.
