My God - we're judging a lot of players on success in conditions that are totally alien, and expectations that are at best unrealistic.
Facing Ashwin and Axar on these pitches is a big ask - yes we could've done better, but some of these players (including batting against spin in SL) are on a hiding to nothing - this is not a realistic test of the skills of Sibley, Crawley, Pope and Lawrence.
I wager that Gill, Rahane, Pant and even possibly Kohli and Pujara would look as stupid as our boys if they batted at Trent Bridge, Edgbaston or a fresh Headingly against Broad, Jimmy, Woakes and Jof (not to exclude Sam Curran). These kids need time to develop in all conditions, over time - before we judge their careers.
