Evaluating rebounding milestones

I’m considering how many rebounds Towns might accumulate, possibly around 7,000, maybe even 10,000 later on. So, if he had about 500 games and debuted in 2015, he might have around 6,000 by 2024, meaning 10,000 seems a bit far off. Instead, I could highlight his milestones with 3-pointers made; he's among centers with good three-point numbers. I want to avoid getting too specific at this point. Let's finalize this!
