I explained very well why I think Chennai shouldn't get a franchise. Incomplete and unfit stadium. Political issues preventing Sri Lankan players from participating. If these two are sorted out, then by all means have a Chennai team. But these are only my concerns, that do not apply in the real world
I think that CSK deserve a franchise, just one where India cement have no role in the team in any way.
They new franchise could even retain Super Kings name if they want, to keep the fanbase intact.
