Clarke was born in Vancouver, British Columbia, but moved to Phoenix, Arizona at the age of three. He grew up in Arizona and attended high school at Desert Vista High School. Although he averaged respectable numbers in one of the top leagues in Arizona, Clarke was under recruited for a few reasons. He was skinny and still coming into his frame by his senior season. There was also a large influx of talent getting national recognition in the state of Arizona, and the arrival of Marvin Bagley took some hype away from all the other recruits.
ESPN had him ranked as the third highest recruit in the state of Arizona and a 3-star overall. 247 sports did not even have a recruiting profile for Clarke. Clarke eventually landed at San Jose State which was the only scholarship offer he received. During his first year at SJSU, Clarke came off the bench with modest numbers, but broke out his second year with averages of 17.3 PPG, 8.7 RPG, and 2.6 BPG. This led to Clarke being named to the first team All-Mountain West and first team All-Defense in the Mountain West. The team still finished below .500 which led to Clarke’s decision to transfer. He chose Gonzaga over Washington State, Utah, Oregon, and Iowa.
After sitting out a year in Spokane, Clarke became one of the focal points of Gonzaga’s Elite Eight team. He led the NCAA in field goal percentage, defensive rating, and total blocks in one of the most complete 2-way seasons in recent memory. Clarke made tournament history by becoming only the third player to total 35+ points and 5 plus blocks in a tournament game, joining David Robinson and Shaquille O’Neil. After the season ended with a loss to National Runner-Up Texas Tech, Clarke declared for the draft along with teammates Rui Hachimura and Zach Norvell.
Clarke was selected 21st overall by the Memphis Grizzlies and was recently named Summer League MVP while leading his team to the Summer League Title. This was done without the other main pieces of Memphis’ young core Ja Morant and Jaren Jackson Jr. Clarke will look to be an essential piece to the Grizzlies future plan and improve certain aspects of his game in a season that looks to be a non-playoff season for Memphis
