Because every player as a specific job. Each player is scattered across the court and if there was any more players it would just be too crowded. You need you space to move around, and work you space. But you do need reserves because its very tiring.
7 players in a netball team
No a netball team has 7 players but you can have reserves which could make up 8 - 9 - 10 or more players
netball is made of 7 players on a team the court and the umpiers
You can have up to about 12 but only 7 on the court at a time, per team.
I am not exactly sure but there are more than seven players including the emergency.
In netball one team has 7 players so in a full game of netball there are always 14 people on court and usually 2 subs for each team.
7 outfield players and some reserves
There are 7 players on each team.
A maximum of 12 players in a team with 5-7 players on court (a game cannot continue with less than 5 players on court).
