With three MLS Defender of the Year honors, more than any other player in league history, Marshall's name belongs among the most distinguished defenders in the history of MLS. Under the steady demeanor and ironman-like durability of ‘Air Marshall’, a number of defensive setups have climbed to the top of MLS in effectiveness. Was named an MLS Best XI for the fourth time in 2018 after receiving the distinction in 2008, 2009 and 2014.

COLLEGE: Marshall spent two immensely productive years at Stanford, starting 39 games and guiding the 2002 Cardinal to the College Cup final. As a sophomore, he was selected to the All-Pac-12 first team before turning pro that offseason.
