Another good example is Greg Monroe, who has only just landed a 10-day contract. In the 90s or early 2000s he'd be a 20-10 guy
He was a 16 and 10 guy only a few years ago!
I don't remember Humphries being that great in the NBL (presumably has improved since), whereas Froling often looked like he could take over from DJ if needed. Hard to gauge his height. He looks big in the NBL, but lists as 205cm on Wikipedia (barefoot?) though 6'11" on a draft site.
Some of the new era of NBA centres have legit size - Porzingis is 221, Jokic 213, Embiid 213, Vucevic 213, KAT 213, Valanciunas 213, M Gasol 216, B Lopez 213, DAJ 211. 6'11" is 210-211 so he's close on a couple of them at least. Baynes is 208.
