The Left Wing got off to a slow start, only scoring one Point in 16 Games (2000-01), and in the three seasons after, his highest-scoring year was 30 Points (2003-04). After the lockout year of 2005-06, McDonald's offensive output drastically improved with an 85 Point year, his best in hockey. He was an All-Star the next season, which was the year that he helped the Ducks win their first Stanley Cup. That would be his last full year as a Duck, as Anaheim traded him during the next season to the Blues.
McDonald scored 259 Points for Anaheim.
