Why are KKR fans not satisfied with Rahane being the captain?

I mean I get the argument that your Captain wasn't your first choice and you shat the bed in the auction. But the point is, you had no better option. Spending that much on the wrong Iyer was a stupid move but it has happened. Now the ball is in your court, do you want to make more mistakes in order to justify your previous one by making Venkateshwar Iyer your captain or try to get the best from whatever you have?

Moreover, anybody who's doubting Rahane's skill should know that he has redefined his playing methods from 2023 and can very well fit in a T20 squad now. Also, I don't need to explain how good of a captain you have to be in order to win BGT with a B team. At least he has his past captaincy achievements to back him over someone who has never captained a team.
