Meagher began attending
Boston University in 1972 but was unable to make the varsity ice hockey roster until his junior season. That year, head coach
Leon Abbott was fired for a second instance of recruiting violations and was replaced by his assistant
Jack Parker. Parker's first four years with the team resulted in BU winning the
ECAC Tournament each year, and making the
NCAA Tournament. Meagher was an integral part of those teams, finishing in the top four in team scoring each year. In his senior season, Meagher was named
team captain and led the team both in goals (30) and points (55). Meagher led the team to a 1st-place finish in the ECAC standings for the first time in five years, but the team was still unable to get out of the semifinals, having lost their third consecutive opening game. After graduating, Meagher matriculated to
Illinois State University and earned a
Master's degree in 1977. A year later he returned to college hockey, becoming an assistant at
Williams before jumping up to
division I with a similar job at
Clarkson. Meagher helped the Golden Knights to a resurgence in the early-80's, winning back-to-back conference championships. In 1983 Meagher received his first head coaching job when
Sid Watson, the long-time bench boss at
Bowdoin, retired. Meagher finished with a stellar record in his first season, going 19–6–1 and finishing as the runner up for the
ECAC 2 Tournament. Ordinarily, Bowdoin would have likely received an invitation to the
NCAA Tournament, however, the
NESCAC, Bowdoin's primary conference, had rules that forbade any of its members from participating in national tournaments. The following year almost the entire
Division II membership dropped down to
Division III and
ECAC 2, Bowdoin's conference, was formally split with the Polar Bears now belonging to
ECAC East. After a down year, the Bear returned in force in
1986, finishing first in the conference standings and winning the
conference tournament. Meagher received the
Edward Jeremiah Award for the quick turnaround and kept the Polar Bears as one of the top teams in Division III college hockey. Meagher received his second national coach of the year award in 1989 when Bowdoin tied
Merrimack, who were about to jump up to D–I. The Bears were typically one of the best teams in ECAC East but it was during the
1992–93 season that Meagher produced one of his best coaching efforts. The Bears were the last team in the conference tournament and faced a dominant
Middlebury squad in the quarterfinals, but the defense held and limited the Panthers to a single goal. The win propelled Bowdoin into the semifinals where they held #3
Connecticut to one goal as well, and they finished off their tournament with a championship victory over
Salem State. The following year the NESCAC changed its policy to allow member teams to participate in one postseason tournament. Bowdoin finished with a good record but decided that it wasn't strong enough to earn a bid to the NCAA Tournament and participated in their conference tournament. The next season saw a similar result from the Bears but Meagher team also saw its first
Sid Watson Award winner when Charlie Gaffney was named as the National Player of the Year. In
1996 Bowdoin finished the regular season with a record of 18–5–1 and took a gamble by passing on the ECAC East tournament. They were joined by Middlebury and
Colby in the gambit and, miraculously, all three teams received invitations to the
1996 NCAA Tournament. Bowdoin ended up drawing the short straw and the team had to travel west to play
Wisconsin–River Falls on the road. Their defense faltered, allowing seven goals in both games and they lost the series rather badly. In
1997 Bowdoin nearly pulled off another upset in the ECAC East Tournament by making the finals as a seven seed, but the team fell on hard time afterward, failing to win a postseason game for the remainder of the decade. In 1999 the NESCAC dropped it postseason prohibition entirely and teams were now able to participate in both the conference and national tournaments. At the same time, the NESCAC also began to sponsor ice hockey as a conference sport and Bowdoin was a founding member of the ice hockey division. Middlebury was the dominant power in the early years of the new conference but Bowdoin managed to receive an at-large bid in
2002. Unfortunately, the team was outclassed by
Norwich, being shut out in both games and being knocked out in the quarterfinal round. Bowdon continued to finish with excellent records in the '00s and made three consecutive conference finals from '05 to '07. The Polar Bears won their first regular season title in
2007 but without a tournament championship they weren't able to make it back to the national tournament.
2010 saw Bowdoin finish with the most wins in 15 years and, despite another runner-up result in the conference tournament, Bowdoin finally received its third at-large bid. The team was given the fifth eastern seed and had to play the #2 overall team,
Oswego State, on the road. Bowdoin's third trip was as successful as their previous two, losing 2–9 and being knocked out in the quarterfinals. The following year Bowdoin dropped to third in conference (tied) but the team went on tear in the postseason to capture their first ever
NESCAC Tournament Championship and their first conference title since 1993. Bowdoin again received the 5th eastern seed, but this time the team earned their first tournament victory with a 2–1 win over
Neumann. Unfortunately, Bowdoin was again unable to escape the quarterfinals when they met Oswego for a rematch, despite the game finishing much closer with a 5–7 loss. Meagher pushed the Polar Bears to the best season in program history in
2012–13. The Polar Bears won the NESCAC regular season championship,
NESCAC Tournament championship and won their second
NCAA Tournament game. The team finished with a 23–4–2 record, setting a program record for wins and finishing with the second-best winning percentage for a program that dates back to
1919. Meagher got the team to its sixth national tournament the following year, but they had to face Oswego again and were still unable to overcome the Lakers. That season Meagher became the 6th Division III coach to win his 500th game. Meagher coached for two more seasons before retiring with a record of 542–253–58 (). As of 2019 he was 21st on the all time wins list for college men's ice hockey and was 9th in terms of winning percentage for coaches with at least 400 victories. ==Personal==
