Loob improved to 37 goals in 1984–85, which was enough to tie him for the team lead with fellow Swede Kent Nilsson. He led the team outright in 1985–86 with 31 goals, and won the Molson Cup as the Flames player with the most three-star selections. Loob struggled the following year due to a shoulder injury that required surgery to fix at the end of the 1986–87 season. He scored only 18 goals while his 44 points was well below the 67 he had scored the previous season.
