Have to disagree here. Johan brought all of Team USA to train in his academy in Russia to prep for the Mosconi Cup. He also had them all compete in a solid-field pro event in Russia called the Kremlin Cup, as he watched and offered feedback. There is no question that the two biggest beneficiaries of Johan's tutelage in Russia were Woodward and Styer, and each performed well at the Mosconi under Johan.
Johan was big on preparation, but once the event began, his biggest focus was on ensuring good sportsmanship, which his teams always displayed.
