If Pant is in the team he needs to play as keeper, which will not happen until Dhoni retires. I feel sorry for Karthik. The guys gets selected in the original 15 but does not get any games, unless India consider him strictly a backup keeper. He is also a better fielder than Pant.
After watching Pant in Australia in 2018?, I certainly rate him as a batsman and he's thoroughly obnoxious behind the stumps which is irritating to batsman and good for the team I think. I would put him in the same category as Maxwell, he won't always make runs and be responsible and will be prone to brain fades but when it's happening for him he's a match winner.
Dhoni's skills with the gloves have been below par in my opinion but I can't see him in the field and Pant behind the stumps.
I feel sorry for WI, so close on a couple of occasions and if not for poor decision making and silly mistakes they would have won a couple of really close matches which would be great for team morale instead of heatbreak.
