Simple..... Senior players want to make big records for themselves scoring against Bengladesh/Bermuda and come to highlight. Even after winning toss, they went for Batting first. All are eying for opening slot becuase they want to build records for themselves not for INDIAN WIN.
Why then experienced players are fighting for opening slot, when they have not came to Indian Team as Opener?
Why are they shying batting down under?
Simple - They are afraid, they may not get chance to score a Century to put into RECORD BOOK.
