It was not like that in any of these cases. The athletes were not responding to the new training programs under these coaches. Charlie was asked to help straighten out the training and fix the problems. He did. Success ensued.
I can vividly remember Charlie saying things like, “How the hell did this athlete get so messed up? When they left me, they were running perfectly well.”
There are more details, but I do not think it is appropriate to dig up skeletons.
