I think the idea that Ramprakash cant the pressure of test cricket is outdated. Firstly, he is a different, more confident and more mature to the player who last played test cricket 7-8 years ago. You dont average over 100 in county cricket if your a bad player; thats even better than what England's current test players average.
Secondly, a major reason why he wasnt up to the pressures of test cricket was because of the pressures imposed on him by the English selection policy of the 1990s-early 2000s. Those were the dark days of English test cricket where they chopped and changed their teams like crazy. I can forgive alot of players from that era to an extent for performing badly because many of those players, in particular batsmen, were constantly looking over their shoulders to see who would get the chop next. I think the English set up today is totally different and would see Ramprakash benefit.
I agree with point 1, but not point 2 although I see where you're coming from.
But I think there will probably be just as much pressure on him for this Test than he ever felt back 10 years ago. Just think, if England pick him, he's 'The Messiah', the desperation call that has to work, the man in irresistible form, and the Ashes may rest on his bat. He will get one shot to succeed, he probably won't be picked again. The expectation on him will be very high and it would take a strong mind not to feel that pressure.
