Need to make bold changes. I think this format requires that more than the longer versions. You can't keep carrying players in poor form for too long. They can hurt the team big in matches that last only 20 overs. We should have been bold enough to replace Gambhir or Rohit with Tiwary.
Besides, captains - all of them - should stop "saving" players in T20s. Raina, ABD, Taylor, Akmal, they all played too low in different games. This pisses me off most when I watch T20s.
