The 1998 team set a Patriot League record for wins with 16 and had the greatest turnaround in the NCAA for that year (+12 wins) Before Lafayette, Lenahan built his alma mater Richard Stockton College into a Division III national power going to the NCAA Tournament in 1993, 1994, 1995, and 1996 and also capturing Richard Stockton's first NJAC Championship in 1996.
In 2013, Lenahan had the rare distinction of coaching in the Messi and Friends game as 10 Northwestern alums were called in the last minute to save the internationally broadcast event from cancellation.
One former alum, Matt Eliason, became a worldwide internet sensation after scoring on a full bicycle kick to upstage the great Messi in the goal of the day.
Eliason, who had been an assistant vice president and investment analyst at GE Capital, quit his job to pursue a professional career.
Lenahan served as an assistant coach for both teams in the match and the film is now available on both Amazon Prime and Apple TV.
