The roots between Washington Wizards guard Bradley Beal and Jayson Tatum run deep.

They’re both from St. Louis. They attended the same high school, five years apart, and both brought home Missouri state championships. They both have great taste and love Imo’s pizza. And since St. Louis is essentially just a big, small town from which you can connect anyone who was ever born there through six degrees of separation, they have another eerie link: Post-Dispatch columnist Ben Hochman recently revealed that Beal’s mother, Besta, was once the University City High School physical education teacher for Tatum’s mother, Brandy Cole.

And here’s photographic proof of Beal and Tatum’s friendship, dating back to a night in St. Louis in 2014.

Beal and Tatum are basically brothers. But since Tatum was selected No. 3 by the Boston Celtics at the NBA draft on Thursday night, the homeboys must now become sworn enemies.

Bitter regular-season matchups combined with seven hard-fought playoff games can make a man reconsider his friends. Of course, Beal was only joking. He only saves his #bOb (built on brotherhood) for his family and closest of confidants, and Tatum still gets the hashtag treatment. However, Beal couldn’t let the moment pass without recalling the Wizards’ tough playoff exit at the hands of the Celtics.

After his “lol’s” Beal expressed pride for his hometown and the high-caliber athletes blooming out of the Gateway to the Midwest.
