Yes, generally older kids are more mature, bigger, faster, and have better coordination.
I find it ironic that parents are worried their child will have to play against older kids( born 5-12 months older) or get knocked down to the 2nd team….while ignoring that those Aug- Dec kids set to benefit…have always had to compete against kids almost a year older.
I always thought the change to BY was stupid..and a decrease in numbers coincided with this change. Especially when kids start in rec, they want to play with their friends when they start.
