I think M Crstn was brought in to manage and stop players from being suspended for minor infractions.
A Sin-Bin would work, as long as it doesn't interfere, with say the Brownlow, for instance. You serve minor abuses in the Bin.
If after the game, it appears the action was worse then just the sin-binning sanction, then another suspension may be added, and that should impact on the best and fairest.
Yellow cards, and Red cards are just too inciteful, & then too heavy generally, and are too soccer.
Not Aussie Rules culturally, and not suited a to a heavy contact sport.
