Ravindra Jadeja surely deserves to be in ATG Indian team.
A batting average of 34, a bowling average of 24(best for any Indian spinner) and an excellent fielder.
Yea it's between him and Ashwin for me - solidifies the tail too, which India have traditionally been weak with, so having one of these two, plus Kapil, really helps.
Realistically, you need a separate home and away (specifically, outside subcontinent) team with India, especially with regards to the bowling options. From a batting perspective, apart from Sehwag/Dhoni, the others are just fine away from home. Maybe an argument for bringing in Laxman. The Dravid opening/Laxman at #3 idea is an interesting one but not tested enough times I suppose.
HOME
Gavaskar
Sehwag (that would have been an incredible combination)
Dravid
Sachin
Kohli
Dhoni
Jadeja
Kapil
Ashwin
Kumble
Bumrah - premature but just even talent wise (and at least producing it for a year) he's just so far ahead of every other Indian pacer, ever.
AWAY
Gavaskar
Sehwag
Dravid
Sachin
Kohli
Dhoni
Jadeja
Kapil
Srinath
Zaheer
Bumrah
Feels weird to drop Kumble away, but all we really need from the spinner away is to hold up an end, and pace is what wins away from home. With Jadeja, the overall strength he brings to the team in batting + fielding is just too hard to ignore. In bowling, away from home, albeit from a very small sample size, he averages no less than Kumble did (though Ashwin has a better average). In batting, away from home, he's done alright in the batting side of things (although only played 15 tests) - averages 30+ vs Australia, England, New Zealand and Sri Lanka.
Interesting to see if this changes in the next ~5 years - specifically if Bumrah cements his spot, and if one of the others (Shami) makes it in at the very least as a contender/option to forcing a pick of one of Srinath/Zaheer.
In batting, maybe Pujara? Hard to see who he can dislodge though - the other opener is the only other 'soft' spot and that's only away. Wouldn't ever drop Sehwag if batting at home. Have a wealth of middle order batting options - could probably field a second XI with a middle order that's pretty damn good...but there'd be a significant drop in quality everywhere else.
Completely hypothetical of course, but I think that away team is stronger than most people realise - it's the Bumrah effect (assuming he plays like he has in the past year). Srinath and Zaheer and Kapil were often asked to lead the attack - however, as bowlers to support Bumrah, I reckon they would have been fantastic (see also, Ishant Sharma and co).
