The shock resignation last week of Pieter Schats from the hot seat of local rugby has prompted the Hong Kong Rugby Football Union to carefully look at the responsibilities the chief executive should carry in the future. Schats announced that he was resigning as chief executive at last Wednesday's meeting of the HKRFU's board of directors. He said yesterday that the reason for his resignation was 'a personal thing' and because he was involved in rugby 24 hours a day. 'I talk about rugby 24 hours a day . . . it was long hours and it got to me. There is more to me than that,' Schats told Sports Post. This full-time involvement has now led to questions being raised as to whether the responsibilities of local rugby's CEO should be shared and delegated to others. HKRFU chairman Peter Duncan admitted that the CEO's job description would be looked at again. The HKRFU is expected to name a successor to Schats within the next month. According to Duncan, there have already been plenty of applications for the million-dollars-a-year job. Schats, who was appointed the first chief executive of the HKRFU in November 1995, has agreed to stay on until the end of June. The unanimous feeling is that Schats was weighed under with too much to do. He was involved with everything, ranging from day-to-day matters to the Rugby World Cup Sevens. In his keenness to make certain that everything ticked, he even took on the onerous task of a fixtures secretary. Hong Kong will take on Wales and a Japanese President's Seven today when the Japan Sevens kicks off in Tokyo. World Cup Sevens champions Fiji, led by Waisale Serevi, are favourites to win the 12-team tournament. Due to the territory's top players being away on national duty, the Foster's Knockout Cup semi-finals between Club and Kowloon and Valley Red and DeA will be played on Monday and Tuesday respectively. However, the Plate semi-finals between Valley Black and Club Dragons and Tigers and Aberdeen will be played today.
