Cottle began his collegiate playing career in the mid-1970’s with Salisbury University. With the Sea Gulls, Cottle was named an All-American three times and still holds the record for the most goals scored in a single game. After working as a graduate assistant for Salisbury and proving himself in the high school ranks with a 26-9 record, Cottle assumed the head coaching position at Loyola University. He led the Greyhounds to an NCAA tournament berth in 1988, a feat he would repeat for 14 straight years. He earned USILA Coach of the Year honors as well that year.
Upon leaving Loyola, he took on the same role at the University of Maryland where he enjoyed similar success as the Terrapins made the postseason each year under his reign. In 2004, he led the team to their first ACC title since 1998 and would go on to repeat as conference champions in 2005. In 2008, despite fielding an attacking unit composed entirely of freshman, he led Maryland deep into the tournament making it to the semi-finals.
Shortly after leaving Maryland, the Bayhawks brought on Cottle as a consultant. During the 2010 season, Cottle helped bring the team out of a five game losing streak to go on and win an MLL Championship.
