Wait, I heard somewhere that the idea was to go ahead and just award 7 for the TD, and if you want to go for two, you have to gamble a point? (i.e., if you miss the try, you get 6, if you make it you get 8, otherwise you get 7).
That sounds even dumber. No one would ever risk going for two in that scenario unless they absolutely needed the point at the end of the game. Make it 6 for the TD and 2 more for the try, eliminate the ability to get 7 or move the kick further back.
Would certainly mess up the scenario books, since you'd never see games in multiples of 7/14/21/28 etc anymore.
