Re: End Zone Catch/Kick
Eh, I think it's pretty good where it's at with the 20. Backing teams up to the 10 would really change the whole game, not necessarily for the better. A 3-and-out gives the other team fantastic field position and makes it too easy for them to score.
The 20 seems like a perfect medium to me; far enough away that it's still a challenge to score, but close enough that it's not too easy for the other team to force a three-and-out and wind up 10 yards from a field goal.
