Pretty accurate scaling I think due to using both ground up height chart and making sure there is consistent basketball diameter between the source pics. List info can be misleading so if yall get curious just how big/small some of these players are most of their actual measurements can be found here:
www.draftexpress.com/measurements
Those that aren't on draftexpress are:
Kobe Bryant:
6-4.75 w/o shoes (From some NY Times article)
6-11 wingspan
178lbs-225lbs (has been playing at around 205 the past few years I think)
Yao Ming:
7-5.75 w/o shoes
7-5 wingspan
276-310lbs
Wilt Chamberlain:
7-1.06 w/o shoes
7-8 wingspan
258lbs-327lbs
And Shaq's info is more precisely:
7-0.88 w/o shoes (according to the newspapers from that time) - draftexpress rounded it up to 7-1 even
7-7 wingspan
303lbs-378lbs
(lol that howard thinks hes superman instead of Wilt or Shaq)
