I was never a fan of Kallis even though i admit he is the most complete player of this era.Infact i believe he should have changed his batting style according to situations and formats.For eg he was too slow y'day to reach is century (115 off 316) which i think not going to help his team cause.There are usually 2 types of batsmen in world cricket.1.Those who are physically very strong (like boxers)Gayle,Pollard,Hayden,Kevin Peterson will come in this category.2.Not physically very strong but having sound technique and proper timing.3.Cook,Dravid,Pujara,Trott will come in this category.Kallis with such a good physique and broad shoulders easily make an entry into the first category but he always preferred to stay in the second one.
Highly likely, Dhawan is flopping on purpose so Gambhir gets a chance. Whatever maybe the reason. We asked before, either rahane or pujara or rohit should be promoted. If rohit cannot perform on top then he can be rested. Dhwana can come low down the order where there is less risk,
