Losses are understandable and upsets happen. Whats unacceptable is to take the loss lightly and not fix the mistakes that were/are being made.
I'm with Zunaid on this that T20 will SOON become the premier form of the game and later become the ONLY form of the game (once the olympics come about and China embraces it).
We CAN NOT be short sighted on T20 and fall behind. WI lost to us in the 2007 WC, bounced back and with the help of the short lived Stanford 20/20, created a team that destroyed ENG in a one off, wend to the semi finals of the next world cup and had a 2nd string team capable of humiliating us in that format.
What did we do? We went about shunning the format and lost to Ireland & WI (2nd team) convincingly and haven't won an internationl T20 match since that 2007 victory over WI.
