Mac McClung's absence from a consistent NBA roster can primarily be attributed to his physical attributes and defensive capabilities. Standing at 6'2”, he is considered undersized for the shooting guard position, which typically requires players to have a combination of height and strength to compete effectively. Additionally, while he has shown flashes of offensive talent, he lacks the elite playmaking skills that are often expected from a true point guard. His lateral quickness and overall defensive instincts have not reached the level necessary to guard the more athletic and taller players in the league. This combination of size and defensive limitations has made it challenging for him to secure a permanent spot on an NBA team, as teams often prioritize players who can contribute on both ends of the court. As a result, while McClung has potential, these factors have hindered his ability to find a stable role in the highly competitive environment of the NBA.
