The architect of one of the most potent offenses in the nation is Seth Tierney, a 1991 Johns Hopkins graduate and a four-year letterwinner for the Blue Jays. Tierney is entering his sixth season as the offensive coordinator at Johns Hopkins and was promoted to Associate Head Coach prior to the 2005 season.

Under Tierney's guidance the Blue Jays led the nation in scoring offense and extra-man offense in 2003 and finished fifth in both categories in 2004. Last season Johns Hopkins finished second in the nation in scoring margin, sixth in scoring offense and 16th in extra-man offense. The Blue Jays have specialized in game-turning scoring runs under Tierney's direction, often turning close games into blowouts. Hopkins scored 14 or more goals in seven straight games and 11 times overall in 2003, and scored 13 or more goals eight times in 2004.

Tierney has emphasized a balanced attack that puts pressure on the opposition at every position. The Blue Jays had six different players score 22 or more goals in 2003, four players score 26 or more in 2004 and nine score 10 or more in 2005.

With the abundance of scoring and talent comes the rewards at the end of the season as eight attackmen and midfielders earned All-America honors from 2003-05.

Kyle Harrison, a 2005 graduate, earned First Team All-America honors twice, won the McLaughlin Award as the nation's top midfielder in 2004 and 2005, became Hopkins' first ever Tewaaraton winner last season and JHU's first Enners Award recipient since 1995. Adam Doneger, a 2003 graduate, garnered First Team All-America honors as a junior and senior, while Kevin Boland `04 and Bobby Benson `03 were three-time All-Americans. In all, a total of 18 Blue Jay midfielders and attackmen have earned All-America honors since Tierney arrived in 2001, including 16 in the last four years.

During his first season at Homewood, Tierney coached a pair of All-Americans in Benson and Eric Wedin. The 2001 Blue Jay offense, with easily the youngest attack unit in the nation (two freshmen and two sophomores), came on strong at the end of the season as Hopkins averaged over 13 goals per game in its final three regular season games.

In 2002 the Blue Jay offense steadily improved throughout the season under Tierney's guidance. The Blue Jays boasted the youngest offense in the nation as three freshmen and one sophomore were counted among the starting attack and first midfield. Still, Hopkins produced a Third Team All-American on attack (Benson) and First and Third Team All-Americans (Doneger, Boland) at midfield.

During his time at Hofstra, Tierney helped lead the Pride to the NCAA Tournament four times. The Flying Dutchmen won 13 games during the 1999 season and advanced to the NCAA Quarterfinals. As the offensive coordinator for six years at Hofstra, Tierney coached seven All-Americans and nearly two dozen all-conference players.

Tierney played for the Blue Jays from 1988-91 and served as team captain as a senior. He helped lead Hopkins to the NCAA Tournament in each of his four seasons, including an appearance in the 1989 NCAA title game. He received the Turnbull-Reynolds Award as a senior as the player most exemplifying leadership and sportsmanship. Tierney was also selected to play in the North-South game as a senior.

Tierney continued his playing career after graduating from Johns Hopkins as he played three seasons of indoor lacrosse for the New York Saints before serving as an assistant coach for the Saints for two seasons.

Tierney and his wife, Maureen, reside in Timonium and have two children; a son, Ryan (7), and a daughter, Erin (5).
