We have had more lopsided games this season. Plenty of games where there was little interest after quarter time. An interesting statistic would be the latest point in the game where you could reasonably say both teams were still in it. Some time early in the 2nd quarter for Brissie.
Anyway, this is a problem for the AFL. Not only are games over early, but the composition of the top 8 is a bit too early. I don't know what you do about it. I'm sure no one wants to be like soccer where the weaker time can score a late goal against the run of play to win the match, but we do need to stop blowouts.
