What's with the rivalry between these 2 teams? Is it just because they're the 2 top teams in the world? And what major guys are on the teams? I know Roger is on Gracie Barra, and Jacare is on Alliance. And which is more popular? I know in the 2004 Roger x Jacare matchup the majority of the crowd was rooting for Jacare. Is Alliance a favorite among fans? Sorry for all the questions.
