I find it odd that some people think you never grow at all after the nba combine. As if they have special machine there that stunts growth so their measuments can never be questioned.
What's really odd is that there are people who think players can get 2-3 inches shorter after the combine, that's what gets me. People can grow, most of them don't.
In fact the human body can get taller all the way to 27 years of age. For real life example a player we kind of documented on several occasions here was Donte Greene. He was 6'9 in shoes at combine and was an easy 6'11 when traded by the kings
Getting taller until the age of 27 is freak one-in-a-million stuff, not every-third-player-in-the-NBA stuff. Most men are done growing by 18, almost all men are done by 20-21.
For the most part, when players "grow" after the combine, especially guys like Ray McCallum who came out after his junior year, any "growth" after the combine is "grade inflation". I mean, Ray was wearing 1.5" shoes at the combine and you'd still have to round up to get him to 6'2" in shoes. That's in May. We sign him in July and he's 6'3"? McCallum, by the way, was listed at 6'1" in high school. So for his first three years of college, after his growth plates should already be closed he grows a maximum of an inch, and then in two months after the NBA combine he grows another inch? At age 22? Nuh-uh.
I'm pretty sure Donte was grade inflation as well, by the way. Much as we wished him to be that tall, he never looked over 6'9" on the court. Grant and Jerry even called out Kings fans for overstating his height on a broadcast once.
