In order to have the greatest maximum potential in sprinting, you need to be tall. Usain Bolt showed us that. Erriyon Knighton is in the process of reinforcing that thought. Fred Kerley is showing us that.
The problem is that sprinting is typically not the sport of choice for extremely tall, athletic people...they're mostly in the NBA.
Sprinting has historically not been thought of as a tall man's game. People think of short, powerful runners with extremely fast turnover. I think it could even be argued that without much specific training, shorter people can have an advantage in sprinting.
But when tall athletes improve their turnover, their greater potential for stride LENGTH is too much for shorter sprinters to overcome. Bolt took 41 steps in his 9.58 wr. Christian Coleman needed 47 steps to run his 9.76. Kerley and Norman take about 42.5 steps on average (greater potential than Coleman in my opinion).
Giannis Antetokounmpo, Kevin Durant...guys like this could probably finish 100m with ~40 steps or less with dedicated training...unfortunately, we'll never get to see what they could do.
