If you have ever read this blog before, you’re probably aware that Austin Rivers is Doc’s son. Austin is the proud owner of the fourth-ranked highlight on this mixtape. The player in the fifth-ranked highlight, Nick Johnson, also has Celtics ties. Nick is the late Dennis Johnson’s nephew. He has kangaroo bounce, and will be headed to Arizona in the fall.

We normally do just one highlight reel a day, but this video was too good not to post right away.

The Elite 24, along with NBA stars Brandon Jennings, Tyreke Evans, and John Wall, got together last night for some late-night hoops at the Hangar Athletic Xchange (HAX) in Hawthorne, CA. Ballislife.com was able to tape the pick up games, which you won’t want to miss. Look out for Austin Rivers crossing up John Wall just past the one-minute mark.

The Boost Mobile Elite 24 is a basketball event featuring the nation’s 24 best high school basketball players. The event will be held at the Venice Beach Courts in Los Angeles on Friday and Saturday. The slam-dunk contest is Friday at 8 PM ET, while the game is on Saturday at 7:30 ET. Both will be televised on ESPNU. Among the participants are Doc Rivers’s son Austin, and Dennis Johnson’s nephew, Nick Johnson. For the complete roster, click here.

Nick Johnson, a 6’3″ guard for Findlay Prep, is the nephew of the late Dennis Johnson, and the son of Joey Johnson, a former Arizone State standout and a California playground legend. Joey reportedly had a 52-inch vertical leap.

“I thought for someone to jump like that didn’t make sense for the normal mechanics of the human body,” Bill Lee, former Lynnwood HS coach, told ESPN Rise.  ”Like he was a danger or could hurt himself jumping that high.”

Nick has inherited his father’s outstanding leaping ability, along with the skills to become a top-flight college player . Nick, the 45th ranked player in his class according to Rivals.com, has recently committed to play his college basketball for Sean Miller and the Arizona Wildcats.

Nick Johnson, a 6’2″ junior guard for Findlay Prep, puts on a delightful dunking display in lay up lines. Johnson is the 11th ranked shooting guard in the class of 2011. He is being recruited by Uconn, USC, Gonzaga and Stanford, among other schools.
