Ouellette plays a much heavier game than his age would suggest, winning a majority of his puck battles against older and larger competition and proving to be an effective cycle player. He was able to extend his touches along the perimeter in the offensive zone using strong puck protection technique, using one arm to fend off defenders and connecting on low risk short area passes to keep cycle plays alive. He was also quick to hound the puck after a loss of possession in the offensive zone by applying pressure to defenders and looking to win pucks back.
