Getting the pelvis over and around the ball of the femur is VERY unnatural. It's rare to see anyone luck into the pattern. Kids will almost never transition, they will just push with their hip until the sport is done with them. What the coach is trying to teach is a special move.This is totally rediculous in my opinion. The body will react on its own in a natural way. It's not something that you have to force to happen. Imo
