Young blood replacing young blood ?

It's over. A record held for more than 3 decades by India was smashed last week. I'm glad to know that BCCI is bringing in new players like Gautam Gambhir, Dheeraj Jadhav, paceman Shib Shankar Paul and wicketkeeper Dinesh Karthik. I'm all for it. We need some young blood. BUT,huh...we need young blood to replace the old, not other young. I felt so bad that Akash Chopra, Yuvraj Singh, Ajit Agarkar and Parthiv Patel were dropped and VVS Laxman, Rahul Dravid, Anil Kumble are still in the team. With bat, Parthiv Patel performed better than the 3 of them. Akash Chopra, Yuvraj Singh and Ajit Agarkar performed in par with these 3 seniors. So why are they still in the team? I'm not asking to sack these 3 seniors. But they definitely need to be dropped for few matches so that they can get their acts together, learn the basics and gain some confidence. I just can't understand the selectors. They always seem to take decisions with just the next 1 or 2 matches in the mind and not think about the future, say the next 3 years or 4 years.
