I was just reading about the 1986 Memorial Cup, and discovered that Rob Brown started his junior career as a defenceman. His first two seasons in Kamloops were played at defence. Brown moved to centre for the 85-86 season to help his draft prospects, because he wasn't considered big enough to play D in the NHL.
Even in his final two junior seasons Brown would drop back to play defence sometimes to get him more ice time. Ken Hitchcock rode Brown and Greg Hawgood hard. One opponent, remembering that Kamloops team, said it seemed like Brown and Hawgood were everywhere, and like they never came off the ice. Which doesn't really seem on brand for Hitchcock, but I guess you play to your players' strengths.
One interesting thing about the 1986 Memorial Cup was that 3 of the 4 teams were coached by Ken Hitchcock, Pat Burns, and Jacques Martin. All were 33 or 34 years old and on their way up. Martin's Guelph Platers won it all, playing a very disciplined forecheck and keeping one forward high at all times. Commentators said the Platers, in their first season under Martin, played with better structure and discipline than some NHL teams. In contrast, Hitchcock and Burns relied heavily on their scoring superstars - Brown, Hawgood, and Ken Morrison for Hitchcock, Guy Rouleau, Luc Robitaille, and NHL vet Sylvain Cote for Burns' Hull Olympiques. The Platers had some top talent too, with tournament MVP Steve Chiasson and captain Gary Roberts. And the host Portland team had a high-scoring 16 year old Glen Wesley, one year before he was selected #3 overall in the NHL draft.
Hull's owner Wayne Gretzky had some free time after being eliminated in the second round of the NHL playoffs. He stayed with the team, attended all their games, was in the dressing room regularly, and strategized with coach Burns.
Martin got an NHL head coach job with St Louis the very next season, having won the Memorial Cup in his only season as a major junior head coach. Burns got the Montreal head job two years later. Hitchcock had to wait another decade before he got the chance to be an NHL head coach, after some time as an assistant and in the minors.
