"The economic impact is already huge from the study we've done," former South Africa captain Smith told BBC Sport Africa. "Our teams have opened up businesses in South Africa. They're employing people. We expect to go from strength to strength over the next number of years. You can touch on travel, you can touch on the hospitality industry - hotels for two months a year - we dominate six major parts of South Africa.
Smith insists the tournament organisers will not interfere in the team selections by the franchise owners and has ruled out a Rooney rule or quota system."We've been very clear from the start that our franchises are investing in South Africa cricket. "With our teams, we are working alongside Cricket South Africa on programs and the investments going into growing the game and developing the game."The SA20 only had a preparation period of five months before the first game of the competition.
