Adjustable baskets.
Great training tool.
Kept raising the hoop as my son's jump increased.
Hoop measured at 9'5" in the picture.
He's 13 years, 4 months old; 6 feet tall, and hasn't hit the big growth spurt yet.
That's about 8" taller than both I and my father were at that age (I finished @ 6'2", father @ 6'4").
This is barefoot in grass in the back yard.
Might be dunking on a 10 foot rim before his 14th birthday.
College might be paid for...
