<P> In the 2012 Ulster Senior Football Championship, all teams except Cavan and Donegal were permitted to advance to the quarter - finals without playing a game in the preliminary round . Cavan and Donegal played each other to determine which would join the other seven teams in the quarter - finals . </P> <P> Connacht and Munster did not make use of a preliminary round, while Leinster and Ulster did . </P> <P> In a Swiss - system tournament with an odd number of players, one player gets a bye in each round, but not all players will get a bye (as there are fewer rounds than there are players). However, as with the case of NFL "bye weeks", these "byes" do not confer any advantage, or in the case of a seeded tournament, that any player / team receiving one is perceived as any better than one that does not, as all of the participants receive one, whereas the awarding of a bye in a single - elimination tournament most definitely does, in both cases . </P>

When did the nfl have 2 bye weeks
