The kid was definately on the pathway to breaking the sub 10 barrier and is still learning his trade. The best skill he may have is an ability to not put limits or barriers in his mind (let the body produce a time…no matter what it is. Therefore sub 10 is just a time not a limit/barrier).
The mind plays many games on a gifted athlete, black or white.
Technical aspects. What is he doing that others may not be? I might be wrong but is there a difference in right v left leg patterning?
