"Excitement," said AB de Villiers, as a media manager tried to quieten the burble heightened by his arrival half-an-hour early for his press conference ahead of today's third cricket Test between SA and England at the Wanderers. Excitement indeed. For the first time since reports surfaced almost three weeks ago - that De Villiers was considering retirement - the media were able to hear how committed he is to the national cause and to the job of captaining South Africa's Test team - in the last two matches against England."For two or three years I've been searching for the right answers, to play less cricket one way or another, to keep myself fresh and to keep enjoying the game," De Villiers said."I have found myself, in the past few years - not very often - not enjoying myself as much as I should be. That raises concerns for me. I've been searching for those answers and talking to people."I'm still very committed - to the job [captaincy]? I'm not sure. The two Tests are all I'm focusing on. After this there's a break of six months from Test cricket. A lot can happen before then. For now, I'm as committed as I can be and very hungry to make a success of the next two Tests."What factors would count when he considered his future?"I want to play for South Africa for as long as possible. I have dreams of winning World Cups and keeping this (team's) No1 status in Test cricket for as long as possible."Royal Challengers Bangalore have secured De Villiers' services for the next two Indian Premier Leagues for $1.4-million a year. De Villiers' Cricket SA contract is said to be between R2-million and R3-million.The maths isn't hard to do. Based on those numbers, De Villiers would make around 10 times less playing for SA than in the IPL.In that sense, what De Villiers does for SA cricket, compared to his IPL deal, is more about national service than professional sport.Maybe money was on his mind yesterday when he joked that he wanted to make England "feel uncomfortable and remind them they are away from home and to not enjoy the pound and the rand currency exchange too much".De Villiers sounds determined to lead SA to a win they need to stay alive in a series England lead 1-0.And he feels that win is closer after the brave draw at Newlands...
