Easily 6" taller? That would mean Baby is 6'4 or 6'5 or Sheed shot up a few inches in his 30's.
My guess is baby is about 6'7, not 6'9 as listed and Sheed is probably 6'10 or so. Hardly 6 inches.
Whatever. Davis is the smallest 6'9" I have ever seen. When we get out of town feeds the announcers laugh every time his height is mentioned. His real height is around 6'5" or 6'6" Rasheed OTOH is a legit long 6'11" guy..
So its about 6 inches. If you count standing reach the amount is probably a few inches more then that.
