Did LeBron ever run a 40?

Yes, LeBron James did run a 40-yard dash. While he has not participated in the official NFL Combine to measure his speed, he did run a recorded 40-yard dash time during a training session. This was done to showcase his athletic abilities and compare his speed to other professional football players. However, it is important to note that LeBron is primarily known for his basketball skills and achievements, not for his performance in the 40-yard dash or any other specific football-related activities.
