Is Sreeshanth's Agression leading to his performance Degradation?

You are right, but thats why he was popular and everyone talking about him. Remember we were not talking about a legend like kumble or sachin. He was not that big guy, but he was popular because of his aggressiveness. www.freewebs.com/arunj_001/cricket.htm

Aggression is good but too much of anything is good for nothing . So sri has to learn from his mistakes and behave well in field .

Absolutely, right that sreeshanth's agression is leading to his performance degradation these days because he tends to lose his mind when his temper rises and could lose his concentration while bowling, i feel that you should concentrate more on bowling rather than his antics.

Sreesanth's beahavior is very poor since he has entered the international cricket. (I dont know how he was in dmestic arena :p) He has involved in sledging with many players. Not only his words cost him much but his actions and gestures like hitting th pitch after taking the Hayden's wicket in T-20 Semifinals was totally ridiculus... He is a player with supreme talent. We have seen this against South Africa in South Africa and also against Australians in T20 World Cup Semifinals. This behaviour is affecting his performances very badly. Match-fines, Meetings, Media, these all things will always be revolving in his minds. He can't give his 100% to his bowling in such conditions. Indian board need to talk to him seriously otherwise India will lose a precious gem...

Aussies themselves are players who behave that badly in the field. They are known for their bad behaviour and abusing the other players of the opposite team. But sreeshanth is somehow behaving very badly and thats not making him concentrate on the bowling. Since he is a aggressive bowler, he needs to dominate the ball in the correct way and he is prone to lost the domination because of such acts and hence he should control in order to concentrate more on the ball handling techniques.
