Dhoni and Karthik both definately. Karthik has done fantastic at international level opening the batting (quite extraordinary considering his poor record in the flat tracks of India, albeit down the order), and Dhoni apparently kept well.
Jaffer seems to be inconsistant and slow but churns out the odd hundred or high fifty to keep the average up. Wouldn't Sehwag do better at this role since he scores 20s where Jaffer scores ducks and 150s where Jaffer scores 100s, simply the better batsman. He also scores quicker and can contribute to taking the shine off the new ball which takes pace off the ball and removes a large amount of swing. As the Chopra/Sehwag partnership showed, defence and attack works well together and with someone although Karthik's innings today was agressive, he is mainly a quite defensive batsman.
India's bowling is, to put it nicely, shocking! Although England Lions is an extremely strong batting team, England are the much better team with such players as Kevin Pietersen and Cook compared to England Lions having Shah and Trott. Sreesanth seemed to beat the bat often but surely he should look to swing the ball in if he can beat the bat often, reverse swing anyone? Zaheer Khan lacked effectiveness and Powar did not show the large amount of ability needed to make India play two spinners in England. So, the verdict on the prospective bowling line up...
Ishant Sharma...NO, too many no balls, those which were legal were not great either.
Powar...NO, sadly, although a great utiliser of F and G, he has not shown to do anything in terms of taking wickets that Kumble cannot do and you have to be special to make a team play two spinners at Lords and he is not that special...yet.
Ranadeb Bose...maybe, such a line and length bowler may be ideal to exploit the slope at Lords and remove batsman with balls which would be played or left with comfort at another ground. On cricinfo commentary, it seemed he was getting a lot (too much sadly) swing and this would obviously help too.
RP Singh...maybe. He is regarded extremely highly by team management and for good reason, he has bounce, a fair amount of pace and a swinging yorker. With the Lords slope, he could take it away from the bat in a troubling way and if his inswing could work in tandem with this, it would be great. And his experience playing at Leicestershire just adds to the list of achievements. Here is another, a strike rate of 46.34 in Indian Domestic Cricket combared to Bose's 55.17. RP gets the nod for me.
Zaheer Khan...yes, sadly, he is still the spearhead of the attack till Munaf or Pathan come back and with a good record in England at Worcestershire, he is a must have in a squad of inexperienced bowlers.
Sreesanth...yes, he is quick, accurate and swings the ball, one of these are needed in every team, a strike bowler. England had Harmison, Australia have Lee, West Indies have Fidel Edwards and Pakistan have Shoaib Akhtar and Mohammad Asif (less pace, but great wicket taking ability.)
Kumble...was there ever a question? The work horse who can work in any conditions, his top spinner and flipper destroys top order and tailenders alike as they fall to a flurry of LBWs and bowleds and until his form starts to fade significently, he should be the first bowler on any team sheet for India.
So, bowlers for me: Zaheer, Sreesanth, RP Singh and Kumble.
