I have been saying there is no harm in blooding young players soon in T20Is... A good T20 team (International team) should have average age less than 25. These guys should stick to IPL (where teams are spread out with all age - all type players) and then you need to form a solid young National Team to play T20Is. So if Rinku Singh and others don't get into T20I team (and not play world cups) then its a disaster and total failure in the purpose of playing/conducting IPL (apart from making money!)
