You have all seen how Dhoni thinks and plays today. His mind thinks "safety first". He hasn't scored a single six and scored run a ball again today. The other day he wanted to ensure India has a decent NRR instead of crashing to 260 AO. That's insurance Incase India is stuck at 11 points as well. Today he ensured India scores above 300. Look at his game against WI. He made sure India gets to 270. Kohli even mentioned that MS knows the par score and doesn't go for 300 and get out for 230 on a 270 wicket. Look at his innings against AUS and how he scored briskly. He got out to Amir going for big runs vs Pak. He will play according to the situation and does what he thinks is best for the Indian team. Add to that his limitations with his age and he knows exactly what he's capable of. Enough of conspiracy theories. Those old legs have one more great innings left in the next 3 games and he will shut everybody I hope.
