Earlier I was also thinking like you but looking at present indian team makeup,I will surely bet for sehwag. Simply, because sehwag is a kind of risk which is worth taking and dravid has done one of the judicious thing by retaining him in the side in wake of coming world cup.
Because, If he gets going like afridi or chris gayle when the field restriction is on he can decimate any side in the world. On this fear psychosis of the bowler, I fully support inclusion of Viru in the indian cricket team. .
