sheesh you basically stop growing if i remember it correctly at 17 or 18. you may grow the odd cm there after if you are lucky.
To put it simply - you're wrong.
It is usual for young males to continue growing (height) until 21-22 and they remain that height until their late 40's/early 50's.
am i. so how much do you grow after age 18. 5 10 cm. or maybe 1cm perhaps 2 if you are lucky. like i said most of us have done our growing by 18 we may gain the odd cm past this point. which is what i said. i say this because i can just the anal retentive types like arguing what was and wasnt said.
lets look at talls on our list who are drafted at 18 19 and what they were at 21 22 shall we.
yeah we will do talls only. just to many to do otherwise.
hmm graham has gone from 200cm 06 to 201cm at age 22. 09.
mcguane 191cm 05 to 191cm age 22.
moore 190cm 03 to 189 at 22.

polak 193 02 to 193 at 22.
schulz 192 to 193. he was there last yr should do pattison as well bet he only gained a max of 1cm if at all.
thursfield 190 to 191.
riewoldt 192 to 193.
need i go on look at players from other sides like roughhead franklin have not grown at all since being drafted.
the norm is at 18ish you have basically done your growing give or take the odd cm.
will you get exceptions to this yeah like in most things.
if a player at 22 23 25 has suddenly grown 2 cm im inclined to think 1 of 2 things either the previous reading was wrong or the current one is.
oh weather this is scientifically correct i have no idea to me its been widely accepted by most that this is so. i have seen nothing to contradict it. perhaps you can come up with players to contradict it but i reckon you will find them the exception rather than the rule.
