Ok so I really thought I knew football, and in the 4th quarter of an online game I kicked the ball off after getting a touchdown to take the lead. So I kicked it off and it bounced out of the back of the endzone, hit the bottom of the field goal post and bounced back in. The next play the other guy was at MY 30 yard line. Is there any rule that on a kickoff the ball is placed at your 30. I don't get it. After that he scored (because he only had to move the ball 30 yards) and I lost the game.
