As expected, Justin Mathes has been named to replace Jay Blossom as the head coach of the Webster Groves High School boys basketball team.

The selection was approved at the Webster Groves School Board meeting on March 11.

Mathes, 28, has been an assistant coach under Blossom for the last seven years, where he was groomed to one day replace Blossom. That day came after Blossom announced he was stepping down after 20 years.

At the time of his announcement in December that he was stepping down at the end of the season, Blossom said Mathes put in his time and deserved his chance to guide the Statesmen, even though he has never been a head coach. Mathes has been a part of Webster Groves’ last two state championship squads, in 2017 and 2018.

Mathes teaches mathematics at the high school. As an assistant, Mathes’ responsibilities included guard development and scouting of the offensive schemes of the opposition. He also spent time as the head Junior Varsity coach.

“I think he’s going to be a great high school coach and I hope it’s at Webster Groves High School,” Blossom said in December. “He’s a great leader. He’s a great communicator. He has a very high basketball IQ. I just think he’d be a great head coach. That’s my endorsement. I know he wants it.”

Blossom, 54, leaves with a career record of 503-193 in 31 seasons as a head coach, which includes 447-122 in 20 years at Webster Groves.

He also helped the Statesmen capture three Class 5 state championships in 2008, 2017 and 2018, win 17 straight conference championships, win 83 straight league games, win 53 consecutive home games and win 20 or more games in each of his final 16 seasons and 17 of 18 years.
