A typical fantasy hockey league or hockey pool, has 8 - 12 teams but often have as many as 20. Other types of pools may have a greater number of teams, which may dilute the average talent making it more or less fun depending on the league, but also represents more closely the actual NHL, which currently has 31 teams. Other forms of fantasy hockey may allow an unlimited number of teams, whereby any number of owners may draft the same player(s). These typically have a restricted number of "trades" where one player may simply be exchanged for any other in the player pool, typically of the same position.
