Worst, for TV and for sponsors, if you mean for real games, we know that break shot is a luck shot, so yea maybe for gambling.
But if you want to make pool a game where audience can watch, i.e. non pool players, then if you make a pushout shot after each break, that would kill it even more than it already is, I mean it is dead right now, but it can even kill it to the point where even pool players don't watch.
How to make pool great for tv? that non-pool players watch it?
Ok, play 7ball, with a screaming audience like the Mosconi, put mics on players and let them have personalities and not be boring, I mean seriously, 7ball with every mistake a ball in hand, and you have one option of playing safe, thats how it should be.
