Simply, they are playing with the sentimates of the millions of ppl.
They are just doing their JOB/Service, which is the source of their bread-n-butter for their family, like we goto office to do our work, they goto stadium to do their work.
They do not even care if they loose the game, they are sure, at the end of the day they will get the money, what ever the result of the game may be.
Instead of concentrating their focus on game, they are more interested in AD films You can not believe DHONI has more than 15-20 product ad films ! Even if he is not able to make 15-20 run in field
Its time to reform .... Pay them if they perform and take fine if they do mistakes/ donot perform.
