Former defensive coordinator Jon Stainbrook returned to the University of Maryland men's lacrosse program as a volunteer coach on Sept. 18, 2008. Stainbrook is responsible for assisting with the Terrapin defense and man-down unit.
Stainbrook spent six seasons with Maryland men's lacrosse program from 1997-2002. During that time the Terps made four NCAA Tournament appearances, including two trips to the NCAA Championship game.
In 2002, Stainbrook's final season with the Terps, the Maryland defense led the nation in scoring defense, allowing an NCAA-best 7.0 goals per game. Goalie Danny McCormick also thrived playing behind Stainbrook's defense, leading the nation with a 6.73 goals-against average.
In 2001, the Maryland defense had another stellar season as one of the nation's top units. The Terps ranked second in the nation in goals against average, giving up just 6.31 goals per game. First team All-America goalie Pat McGinnis and second team All-America defenseman Michael Howley had rock-solid seasons in helping Maryland to its near-record performance.
Maryland's man-down defense was also one of the nation's best under Stainbrook, killing off 81.9 percent of the penalties without allowing a goal in 2001. The unit ranked third in the nation by holding opponents scoreless in 77 of 94 chances with an extra man.
During his previous stint at Maryland, Stainbrook coached several USILA All-Americans on close defense including: Dave LaChapelle, Chris Lamy, Casey Connor, Michael Howley, Chris Passavia and Lee Zink.
Stainbrook joined the Terrapin staff in 1997 after serving as defensive coach at Division III power Nazareth College. Stainbrook helped lead the Golden Flyers to a 36-6 record over three seasons, including three consecutive NCAA semifinal appearances and the National Championship in 1995.
