Hawks had good matchups ad the wings fell into the matching trap. Simple as that, they wont have to deal with it next game and wont make the same mistake in game 7 if it occurs. Hawks are on the edge of elimination, game 5 is going to be their hardest push i think.
Problem is nobody teaches these kids how to check or how to take/avoid one. And kids at that age aren't out there to kill one another I would be willing to bet 90% of those injuries come from illegal checks or situation where the player being hit was unprepared.
