I don't like the 6 again rule, there is definitely more injuries as a result of it, which in turn affects the weaker teams more than the stronger teams who have much more depth in their squad. Also if you haven't got a few superstars in your team you will struggle much more than before, an average footballer can handle a superstars much better before becoming fatigued hence the score blow outs towards the end of games, (no use blaming it on the players lack of fitness).
My theory is that the NRL wants to reduce the number of teams with 4, 5, max 6 teams in Sydney, I'm sure that this is what Politis wants, and if he isn't already he will make V'Landys his puppet.
