[5] His first two recruiting classes lay the foundation for UNH's success in the 1990s, included NHL players Chris Winnes, Adren Plavisc, Kevin Dean, Scott Morrow, and All-Americans Joe Flanagan and Domenic Amodeo, and Hockey East all-stars David MacIntyre and Savo Mitrovic.
[6] Another long-time UNH assistant, Dave O'Connor filled in for Kullen, but the team was predictably flat in his absence.
Kullen returned behind the bench the following year and continued the work he had started, getting the team to 12 wins in 1988–89 and then followed it up with a 17–17–5 mark, their first .500 season since leaving ECAC Hockey after 1983–84.
While he was expecting to continue coaching for the foreseeable future, Kullen began rejecting the transplanted heart in the fall of 1990 and was forced to turn over the team to Dick Umile to recover but he died about a month later on November 2.
[8] in 1991 Bob Kullen became the first player to have his uniform number retired by Bowdoin College in the history of the athletic department.
