Leonard was selected 45th overall in the 2002 MLS SuperDraft, and signed to a developmental contract. After spending his first year entirely on the bench,[3] Leonard came on strong at the end of 2003, appearing in ten games, including five starts. He developed into a consistent starter in 2004, and when Joe Franchino went down with an injury, Leonard took his spot at left back; he finished the year with one assist in 22 starts. In 2005, while playing most of the year at the left wing spot, he scored a goal and an assist. He was waived by New England in 2007.

But the African-American from Georgia never expected to discover that his roots trace back to Finland and Asia."
