Yes , those guys are freaks , they can do crazy dunks on 10' easily...
But those dont look like 10'
Or the guys are taller than what they say.
Im thinking both.
So if someone is ~6' in shoes , he would be ~5'10 barefoot , claiming 5'9'' ,i guess the same for reach , bend or lower the rim 1 to 2 inches too and there you go , you "stole" ~5''.
Not hating on them anyway , its obvious they are all above 45'' RVJ.
