Kenyon Martin Jr. Recruiting LeBron Jr., Come to Sierra Canyon!

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. Also, Marvin Bagley -- the #2 pick in the draft -- just graduated from SC.

As we previously reported, LeBron's son, Bronny -- widely considered the #1 rated 13-year-old hooper -- is seriously considering going to Sierra Cnayon ... but nothing's in stone yet.

But, Kenyon Jr. is hoping he can help steer Bronny in the right direction -- it's a pretty good sales pitch.

Obviously, they won't end up playing together -- Kenyon graduates in 2019 ... and he's already getting offers from top colleges including Georgetown, Memphis, Oklahoma, Oregon State and UCSB.
