From India'a point of view, the shining stars of this season till now have been Rinku Singh and Yashasvi Jaiswal.
Yashasvi will have to compete with Gill and Ruturaj but being a left hander will give him an advantage. Kishan seems a minnow basher but not ideal first choice player vs top teams.
Rinku is a long term prospect for finishers role because he keeps his body position still and has the range to hit the boundaries in the final overs. In India's T20 setup, he can come in at 6 with Pandya moving up at 5.
Kishan is a hack. He has some talent in hitting, but his shot selection is worse than Rishab Pant.
Jaiswal will not get a chance until senior statesmen like Rohit retires. Ideally I would want Gill and Jaiswal to open in T20's for India. Rinku Singh has a lot of talent to hit big down the order. He needs one more super successful IPL season under his belt to get his opportunity.
