By Brian Kendall. Many young basketball players dream of playing like LeBron James, dunking the basketball, throwing alley-oops, swooshing 3-pointers and winning the game on a last-second shot. The problem is, with a short stature and a limited skill set, children can't live out those dreams on a 10-foot basketball rim. In fact, many children younger than 10 lack the strength required to propel a regulation-sized basketball to a rim that's so high.
