Each ERA (DB/Pre/Post/Exp) would contain the following teams:
Philadelphia Phillies A's/Royals (Philadelphia/KC/Oak) Boston Chicago White Sox Chicago Cubs NY Yankees (incl Highlanders) Giants (NY & SF) Brooklyn/LA Dodgers Pittsburg Cinncinatti Detroit Cleveland St Louis incl Browns Washington/Balt/Minn NY Mets Angels and Padres Milw (Braves and Brewers)/Atlanta/Florida Toronto Montreal Texas/Houston Colorodo/Arizona
There are 21 teams, but each has a DB, a Pre-war, a post-war and an expansion team - so that would be 84 possible teams. And everyone can draft 2. Hope that's clear to everyone?
