What will Miles the midfielder produce?

After missing the AAMI Community Series game with a minor foot ailment, Bergman is set to return for Round 1 and looks set to be unleashed in the midfield. Signed a two-year contract extension last year after courting interest from Victoria and at 24, is entering his prime years. Gets the ball going forward with great intent and should complement the crash-and-bash of Zak Butters and explosiveness of Jason Horne-Francis. After a sparkling start to his career off half-back, he's a player the Power need to pop if they are going to get a boost in Josh Carr's first year.
