The 2011 Volkswagen MLS Most Valuable Player was always going to be controversial. There have been many arguments for and against the Canadian winning the MVP award. In 2011 he played for 3 teams, Toronto FC, New York and D.C. United. The bulk of his season was spent with D.C. United and it was there that his case for MVP was made. While United may not have made the playoffs, it's easy to say that without De Rosario, they would never have been in the mix.
In addition to the MVP award, DeRo also won the MLS Golden Boot this year. His 16 goals and 12 assists certainly support his cause. Major League Soccer was wise to release the numbers of MVP voting, which can be found here.
