Why has the bigot dhoni rested sachin?

Ah, there u go again after Dhoni! C'mon he knows wat is he doing and he doesn't need anyone's feedback! There is nothing like junior & senior!!! And Dhoni is there to think for the Indian team not for any individual! And Sachin after being given out 3 times in a row due to bad-umpiring decisions needed some time. Dhoni had said he would be resting his "KEY" players, there is so much of cricket going around now a days & team India has a busy schedule ahead in NZ, perhaps, Sachin needed sometime out and be prepared for NZ tour as they had already won this series!
