"Throughout their history together, Ronaldo Jacaré and Roger Gracie faced off five times. Roger won the first, in the absolute brown belt final of the 2002 Worlds; Jacaré drew even in 2004, in the aforementioned final where he broke his arm; the third came at the 2005 European Open, with the Gracie taking a narrow win; then came the 2005 ADCC, where Roger submitted Jacaré; and to wrap up, there was the absolute black belt final at the 2005 Worlds, where Jacaré edged Roger out with a controversial decision."
Roger got the better of their contests (finished him/broke his arm in a loss), as well as is pretty much well known as the greatest grappler alive right now throughout the jiujitsu world
Jacare did leave earlier to compete/focus on MMA, so that definitely plays a role in it
