11 of Leinster's 12 counties play in the Leinster Football Championship. The exception is Kilkenny.
yes there is a minimum number of teams to have a conference championship game. i might be wrong, but i believe it is 10. the big ten will no longer have a conference chapionship game.

Because Hurling is very weak in Connacht and there are no teams capable of mounting any serious challenge to Galway there, they have been allowed into the Leinster Championship. The counties there that participate in the Leinster championship are of a higher standard, though not all Leinster counties participate as some of them are also of a very low level. So having Galway and also Antrim from Ulster, competing in the Leinster championship has made the Leinster Championship more competitive and given better challenges to Galway and Antrim than they would get in their own provinces. Until the standard of the other Connacht and Ulster counties improves, they are not going to be a challenge to Galway or Antrim respectively.
20 teams in the premiership.Twenty. Three are relegated each season, and replaced by three from the Football League Championship.
