The fact is that because of our poor running between the wickets and poor fielding, we would always be -25 if Batting first meaning if we score 150 in 20 overs, the other team will feel they have to score 125 to win.The other 25 runs will be donated by our fielders. In case we chase, because of poor running between the wickets, a score of 150 would be like 125 for the opposition, meaning the Opposition would be 25 without starting their innings. A very uphill task for our team against athletic teams like Australia, South Africa, Enland, New Zealand and Sri Lanka. We will always have a chance against Pak, West Indies and Bangladesh because they are slower than us.
