University of Maine center Tim Doherty was not pleased with his play during the 2018-19 campaign even though he tied for fourth on the team in scoring. He collected nine goals and eight assists in 36 games but was a team-worst minus-14 in plus-minus, which awards a player a plus-one if he is on the ice when his team scores an even-strength or shorthanded goal and a minus-one if the opponent scores a goal. The 6-foot, 190-pound native of Portsmouth, Rhode Island, used that statistic as motivation for this season, and it has paid off. Doherty is UMaine’s co-leading scorer entering this weekend’s Hockey East series at Northeastern with six goals and eight assists in 12 games.
