Managing individuals doesn't mean if a player thinks he's above the other 20 players in the team on the day, he can pick and choose what positions he plays.
Thats like me sitting at back pocket and watching our forwards struggling, then just moseying up and having a crack up forward coz i think i would do a better job.
That shouldn't happen. Thats why the coach has the magnet board, and not the players.
From the outside looking in id say the team/individuals were managed pretty well considering the key forward kicked 117 goals, and the team made the Prelim in its first year in a tougher division, 12 months after playing off in a GF (be it unsuccessful).
Seems like the coach knew what he was doing (from the outside looking in, which is what you're doing too)
