I know there is a lot of discussion on Kohli as a slip fielder and why he is not suited to that role. There are two things he does as a fielder that are great if you are an outfielder or at least a ring fielder but that are absolute no-nos as a slip fielder. He stands up early and tries to anticpate and goes for the ball. None of those attributes help, as a slip fielder. But at least with respect to the staying low part, I feel it is not something that will cost him in bouncier conditions like Australia or South Africa. As long as he can sort out his going for the ball instead of letting it come to him, I think he can do a decent job there.
Ideally though, if all goes well, we should have Vijay, Rahul and Ashwin as the 3 slips in that order, Rahane at gully and Pujara at short leg for the seamers. For spin, I will have Pujara and Rahul under the helmets either side, Rahane at slip, and Vijay as the gully fielder. Kohli will probably be ok as the leg slip in that situation as the anticipation part plays more of a role in that position.
