Absolutely I?ve been a coach at Maitland 13?s for the last 3 years ( currently have the 12?s and going back to 13?s next season) your asking kids to make the step to the full size field and in one year try to potentially displace players in 15?s who have had 2 maybe 3 years of it. And depending oh your 15?s as I said before every second year you either have a young 15?s so hardly any spots available or an older 15?s so a heap of spots. When it?s the 15?s are young do you drop a girl turning 15 for one of the 13?s coming up do you stick with the girl turning 15 or potentially force a girl into 17?s before she is 100% ready. So yeah either change 13?s to 14?s or add a 14?s in as well as 13?s as the numbers are growing. Then over time add a 16?s and 18?s.
