I will be touching on the two most important roles:

First and foremost, the position of clubhouse leader will be taken over by the former user, Dr Spray. In addition to being the best teammate and all around inspirational figure that he was, he was most importantly a trailblazer in the analytic-intangibles crossover in SHL history. As the inventor/creator of the "Fast/Attacking/Supportive" metrics and chart, he made it easy for anyone to look at a quick graph and see who worked the hardest and who was the best teammate. Grit/60 was an early stat tracked by him, and led to many, MANY, many, players being overpaid by their GMs. As far as I know.

The scout role will be headed up by Ace. I have never seen someone with such a vast knowledge of players and an eye for potential. This guy should be in charge of every team's development. Or, he should be if he wasn't a GM of a team already, which would probably be a conflict of interest. Anyway, he'll be leaving that role on his favorite team to be a scout in this scenario.
