Once again Bonn had the pleasure to dominate a league almost at will (only against RC Bielefeld there was a 22:24 defeat). So the RCBRS started in the following year in the regional league NRW, and also here they did very well, so that they could establish themselves in the upper midfield. Especially from the 2005/2006 season on, the RCBRS was able to join the top trio of the regional league together with the RC Aachen and the Düsseldorf Dragons, but for the time being without being able to maintain the top position. In the next season, the team was again so broadly positioned that a second team was additionally entered in the NRW Verbandsliga. In the 2008/2009 season, there were wild ups and downs, with both a 0:76 against Elmpt and a 95:3 against Münster, the results could hardly have been more contrasting. The season 2009/2010 should then very successfully on place 2, with only one point behind the RC Aachen conclude, so that one in the consequence into the newly founded 3rd Bundesliga South-West Promotion. For various reasons, there were many player departures to cope with, so that they had to compete with other players again and again and ended up with the 8th place on the penultimate place. Due to the thinning of the roster, the second team had to be deregistered for the 2011/2012 season. This and a lack of consistency in the interaction of the men’s team ensured that the transitional season (some youth players are to be integrated into the men’s team) was completed in 6th place. Due to the league reform in German rugby, the men, now called “The Lions”, competed in the 2nd Bundesliga from the 2012/13 season. For the 2015/16 season, however, the men decided after some disastrous results to start again in the regional league to make a fresh start here. The current team builds on a solid core of players from recent years, and is getting better at integrating new players.
