Google wont help Biff, I'll give it my best shot and start all over again. You have to look at it from a rugby player career point of view in SA. U19, U21, Vodacom, CC, S14, Springbok.
Area wise the Stormers is suppose to be Boland & WP, Sharks is Sharks, Bulls are Blue Bulls,& Pumas, Lions are Golden Lions , Leopards & Falcons, Cheetahs is Cheetahs & Griquas.
Practically it dont work like that because you S14 franchise receive more money and they will draw the top players.
The next level of players will be in the smaller brother province. Meaning that if the Kings get the nod, all the top players that dont have a S14 contract will move there to earn a better living.
In NZ you have a total different setup where your top 120 players have central contracts and is spread over their NPC provinces.
