Yeah bro, its called professionalism. They are professionals. They cannot do anything more than playing cricket. If you feel that they are 'relaxed' as you put it, you are way-off the target, bro. When theya re dropped and are in the wilderness, they go thru the same insecurities that you so dramatically illustrated for a middle-class working man. And if they get paid for it, then they have deserved it mate. If you thing winning an endorsement is easy money, try to make your mark in cricket and see. Right from sub-junior, junior onwards it is cut-throat competition. There are a million Dhonis on the street, but from there to lift yourself and come up requires enormous amount of dedication and perseverence. Dont feel that the big bucks make them 'lazy', to get to the 'big bucks' they have sacrificed their pound of flesh, not to mention lots of idle time.
So chill mate and do feel like 'things' came easy to the boys....They deserve it...and about winning and losing, it all a day to day process. Even Australia has seen bad days, so dont just grind them to the dust....RELAX...
