When I worked with young Elite sports people, we used to screen not only the young person, but their parents, siblings and significant others.

No point in wasting a valuable space and money on someone who may have talent, but the wrong mental approach and attitude.

Becoming an Elite sportsperson takes a lot more than raw talent.

They 'have' to be able to deal with uncomfortable or difficult situations and deal with what they perceive as pressure.

If they couldn't deal with those, then they were gone.
