To answer your first question, he probably just didn't have the personality for the show ring. Sometimes you have to put them in a few shows to see how they do. Even a seasoned show dog will sometimes lose the "zest" for showing.

My Matty, for example, has a sire who is a champion and she is full of personality - until you put the lead on her. It doesn't really matter because she is too small to show anyway.
