How would you change the overtime rules?

I heard on one show that its like 53 to 47 % that the team who wins the coin toss wins the game. That did not factor in the team punting away then getting the ball back and scoring on their second drive so that even makes it closer. I don't think its that big of a deal but I could see them allowing both teams a chance with the ball then its who ever scores next.
