Dhoni doesn't warrant a guaranteed Test spot

He [Dhoni] has failed dismally to rally the troops in two disastrous overseas campaigns and his suspension from the Adelaide Test is almost a blessing in disguise. His own form, not just with the gloves but also with the bat no longer warrants a guaranteed place in the Test side and Wriddhiman Saha has a glorious opportunity to make a big impression in the fourth Test. As for finding a new Test captain, there are no obvious choices from those players who are likely to remain.
