re: What rule would you like to see changed?, if you had the power, it can be any sport

A fumble into the endzone that goes out of bounds and isn't recovered by the defense should not be a touchback. It should be loss of down and placed back at the spot of the fumble. A touchback is far too punitve of a rule. Why should the rule be any different for going out of bounds in an endzone vs out of bounds anywhere else on the field?

For example a first and goal play from the one that gets fumbled through the corner of the pylon results in a turnover PLUS the defense gets the ball at the 20 instead of the 1 where it was fumbled. And the defense didn't even recover the ball! It's by far the worst rule in football.
