My Proposal

So, as expected, India lost the first test against Australia.

Sehwag, who clearly had an inside edge, was given lbw my Mr Bowden.
Sehwag, clearly showed his disappointment by brushing shoulders with the umpire, and now he has to pay 65% of his match fee as penalty for his 'mis-behavior'. This reminds me again, of some changes that has to be brought into cricket.

I propose 3 changes, which is sure to make the game of cricket more interesting.

(1) Challenge : The teams should be allowed 2 challenges. When the umpire gives a decision, which the team/coach feels is an incorrect decision, they should be allowed to challenge the decision. And third umpire should come into the picture.
(2) Distribute Field Restriction : One day matches has the field restriction for the first 15 overs. I believe making the field restriction more flexible, just say, make it 3 session of 5 overs each, and the fielding team captain can choose when to apply each of the 3 sessions. This will definitely make the game more interesting by having an additional strategy to think about.
(3) Timeout or Communication : The coach, should be able to communicate with the team by timeouts, say 2 for each team, or should be able to be in touch with the captain by wireless.

These 3 changes will definitely change the game for better and make it more interesting.
