Growth stops at 18. In some very rare situations growth can continue until very early 20's. I googled it so it must be right.
I was going to say until she's gone through menopause...then stops trying at all but it's probably more like, when your heart stops pumpin' at capacity and filling those arteries! (Or the little blue pill kicks in)
Simons at his predraft measured 6'2.25" barefoot, 183 lbs, 6'9.25" wingspan, 8'3.5" standing reach. If he hasn't grown, he's best matched up on PGs defensively. His listing by the league is now 181 lbs. If so, he's giving up a lot of bulk when matched up on wings. Dame and Hart should provide good eyeball reference next season to see if this speculation he grew holds any water. Both were 4 year college players & so very unlikely to have grown more after their respective combine measurements in their 20s... Lillard measured 6'1.75" barefoot while Hart was 6'3.75" STOMP
I think it was the movie Citizen Kane where they put cameras on the floor and shot everything pointing up making it seem magnified. Something about the way they shot it was never done before.
