On Day 1 performance, I would give CSK a 7/10.
Great picks: Rahul Tripathi, Rachin Ravindra
Good Picks: Devon Conway, Ravichandran Ashwin
Average Picks: Noor Ahmed, Vijay Shankar, Khaleel Ahmed
I felt that CSK splurged a bit too much on Noor Ahmed, seeing how frugal they were after that! Vijay Shankar and Khaleel have a 'not so good' reputation, but I wont call them bad picks because CSK have a glorious history of turning mediocre and past their peak players into IPL powerhouses. Thats why that extra point to take us to 7/10 for Day 1.
Plan of Action for Day 2: Need quite a few bargain picks, especially among seamers and an additional overseas batsmen (preferable an allrounder).
