i think sportsmen are a little bit nervous due to these brand ambassadors ..............n how come they judge players ..i think only a professional sportsmen can read a player till some extent ...players should never be seen in the point of view of cosmetics or goods.due to these activities players lose their hope in some cases...i have a good example for this south Africa cricketer Hashim Amla plays for the country n not for money..as cricket south Africa isn't paying him money as he opposes the branch which is related to one of the alcohol companies so i can say that players are there to play for the country but due to some ambassadors they are being forced to play a game which is not a sportive men sport..
