Clarke was left off everybody’s draft board before the season, but was able to flip the script with an all-around dominant junior season at Gonzaga. His athleticism will be his calling card in the league, and his offensive game holds potential for growth. Being 22 already is a negative because he will need to develop quickly in order to stick around.
