Most of the current T20 leagues around the world are very new and the playing rosters are typically not settled; players change teams a lot between seasons. In addition, many players play in a lot of these leagues, often for only brief periods such as a few games at the start and end of the season only due to international commitments.
In these cases, what determines the eligibility to play for a team in the CLT20? Is there a minimum number of games or is playing just 1 game enough? What if a player was contracted to a team, but didn't actually play any games due to injury or form? Maybe there are no rules at all, and the franchise can bring any players they can managed to hire along to play the CLT20, even if they have never played for that team before? If a player played for a team in a previous season, but not the one in which the team qualified for the CLT20, can they play?
