‘MacArthur, 24, went from the Sabres’ 13th forward to a key contributor early last season, even subbing at center in the fall as the team battled injuries. Six of his 17 goals came in the opening 13 games of his first full season. But he also slipped after his torrid start, earning a spot in the press box. He finished with 31 points in 71 games and was a minus-4.’
