Kenyon Martin Jr. is like a Magic Johnson Jr. when it comes to LeBron James Jr. -- putting on the full-court press to get him to commit to his insanely high-profile California high school.
Of course, Kenyon -- one of the top high school players in the country -- is going into his senior year at Sierra Canyon ... playing alongside Scottie Pippen's son and other NBA spawn.
The school's basketball program is crazy famous -- drawing super high-profile fans like Drake and Kanye West.
