I completely understand your point, in that it would provide better competition within the team, which would them force the players to get more out of their playing abilities. I think this is the only way to manage your team whilst you are competing for the ultimate prize. But i still believe to get the players into a position where they will be best prepared for that time, they need to play consistently against the best opposition. Jack Watts as a junior, against bodies that were of similar size to his, was a dominant KPF, so he needs to time to adjust to the bigger and stronger afl hardened bodies, which he can only get through games experience
