[Tom Molloy]

When I was In Junior High and High School ages 12-18 school the school sports categorized players using the McLoy system which was a formula based on age, height, weight. You played Junior varsity if you were under a certain score. If you were really close and a dominant player they could move you up to Varsity.

The formula was.
20 x age
6 x height in inches
+ weight.

The age included monts somehow so if you were 14 in June and they figured it out in Sept it was 14 + 2/12 x 20

I think this was a great way to even things out and prevent a 5'2" 110 lb. playing football vs his 6'2' 200 lb. friend.

I grew really late i.e. 5'2" and 100 lbs. at the start of grade 10 and was born at the end of October, so I usually played JV an extra year vs people more my size. I was lucky in hockey and baseball two non school sports because the cutoff date for age at that time was Aug. 1 and not Jan. 1 as most sports are now. So I was in the first 3 months and not 11 months younger.

Size differences are the biggest in the early teens and the key is always who fills in at the chest first. If a player has a large chest and broad shoulders then he isn't going to grow much more. Body hair is also a big indicator. Under the armpits, groin, face indicates an early maturer. If your 11 year old phenom centre has to shave between periods he probably isn't going to get much bigger.
