"Say What Now????": LeBron James Shares Son Bronny's RIDICULOUS Dunk, NBA Stars React

LeBron James is many things to many people, but when it all comes down to it these days, "proud dad" is probably the best description you can lay on the 4-time NBA champion. 

His son, 17-year-old high school sensation Bronny, showed off his ridiculous hops with a slam dunk contest display that LeBron was quick to post on Instagram, and it was just as quick to get reaction from all over the basketball world. 

With his head at the rim, one estimate pegged the bounce at a 44-inch vertical. 

One of the most notable reactions came from Golden State Warriors superstar Steph Curry: "Say what now????? Sheesh." Dwyane Wade, Chris Paul and Kendrick Perkins were among the others dutifully impressed by Bronny's big ups. 

The only thing left now is for the newest member of the James gang to go pro. LeBron has already been weirded out at the fact that he's faced Bronny's former high school teammate in the NBA, Ziaire Williams, as well as another high school opponent, Evan Mobley, who's making his mark big-time this season as a rookie. 

As James captioned for Bronny's dunk: "Scary hours coming soon!!"
