Winner breaks is what the fans want, as packages make for exciting pool, but with these rules, I'm not sure it's sensible.
This is stupid if you really think about it.
Imagine if in football the scoring team retains possession of the ball and gets to receive the kick off. You might get to see a team score 5 or 6 touchdowns in a row without the other team ever getting possession of the ball. Imagine if if were a race to 35 points. One team might win without the other ever having touched the ball. That sure would be exciting huh?
Imagine if the scoring team in basketball kept getting possession of the ball after every score until the other team was able to able to steal it and score? We might get to see a team rattle off 25 or more baskets in a row before the other team ever touched the ball. Wouldn't that make for some exciting basketball?
Imagine if in baseball it was a race to ten runs but there was no provision for the opponent getting an equal number of innings? You might see one team win with ten runs in a row without the other team ever having been at bat. How exciting huh?
There is a reason almost every major sport in existence has rules that stipulate that both sides get an equal number of chances to score or that the next possession goes to the other team after a score. Because it is stupid. It isn't fair to the players or the fans.
And although it adds excitement in one respect, it loses excitement in another. I mean yeah, it might be nice to see a team score 5 touchdowns in a row in football and win the game without the other team ever having ever had the ball, but on the other hand there wasn't the excitement of a battle, or of getting to see both teams attempt to be offensive. It might be cool to see 25 baskets in a row from a basketball team before the other team touches the ball but then you don't have a battle and miss seeing offense from both sides. The only reason people want winner breaks with pool is because that is what they are used to, the tradition, part of the game's identity, its all they know, it is just how it is and always has been. If it went exclusively alternate break for a number of years once people got used to it they would never want to go back to winner breaks, just like they would never want football or basketball to be a game where the scorer retains possession.
