Craziness. My 7th grader turned 12 two weeks ago. His friend, also a 7th grader, turns 13 tomorrow. My son is barely 5 feet. His friend is 5'8". That's the difference between pre-pubescent and post pubescent. In this age range size dominates athleticism and good stick skills. Yes, it will equalize as the boys head into 9th grade but for this period of time it is a killer for those on the young side and puts them at distinct disadvantage. And the fact is that it's much harder to lose a spot on a good team than it is to win that spot.
