Well to be honest, ganguly is the only batstmen i can see murli hitting on the long on stands tomorrow. So letting him come down the order shouldn't be seen as a demotion in any way, we want to see him capitalizing on his strengths. Also this is just a make shift for tomorrow's match. And in one of the matches against lanka when he was a regular opener and captain, he him self demoted himself. I am pretty sure this was the reason then.
