I suspect you haven't watched the last few India matches.
The SA collapse was due to pressure of being 270 for 1 in 40 overs? The England tie was due to pressure after putting on 338 on the board? Or the bit where we came back from dead in the game to tie it? Or was it pressure that made us win against Bangladesh, Netherlands and Ireland? Be more specific.
Evidently you don't understand the difference between shit cricket and choking due to pressure.
Pressure is having to bat out 2 days to save a game in Napier, having to bat after NZ have piled on 600+ in India batting first, having to bat out a day on a cracking, turning pitch against SA away in the final test, having to come back from 1-0 down away to Sri Lanka with half your side out injured. Been there, done that.
And if you want to argue about the ODI record, they've won about 6 out of the 8 series they've played under Dhoni or something very high like that, one of which included Harbhajan smacking a six off the last over against Pakistan. After that, we played Sri Lanka and chased down totals of 290+ with ease after the top order including Sachin had fallen.
Anything can happen, and maybe we'll fall victim to pressure, but to say this team doesn't have bottle is absolute nonsense.
