I think their local players are pretty strong.
Jadeja and Dhoni have been IPL stars since the tournament began, Gaikwad has been one of the most consistent batsmen over recent years, Dube seems to have found his role in this side and was a key part of their success last year, Chahar and Thakur are both international bowlers and the CSK management know their games and how to get the best from them, then you’ve got Rahane who looked like a weak link last year but had arguably his best IPL season ever.
That’s 7 capped Indian players to play alongside the 4 overseas picks and they still have some very talented uncapped options too in Sameer Rizvi and several seam bowlers who they can rotate to suit conditions.
Your actually right. They should at least get to the final. Let's see and hope for the best.
