Can't they bid for the same players again even after releasing them?
Yeah they can do that. But now that CSK are champions and also all the teams have seen all these players perform in the IPL, the perception about a player's value has changed among the franchises. For example, Vijay/Ashwin will be really sought for after what they have done for Chennai. So chances of Chennai retaining them is 50-50.

I'm just failing to understand something. What do you mean by releasing the players who have BCCI contracts? Doesn't Dhoni come under that as well?
Yes, but Chennai can retain upto 4 players for $5.5 million (1.8 million for 1 player, +1.3million for the second, +900k for the third and +500K for the fourth). Dhoni justifies the $1.8 million tag and so there is no way CSK wont retain him. CSK can retain Vijay and Ashwin too but that means they would have spent a huge price to retain their services.
