The team would not return to Serie A until the summer of 1974, with the victory against CUS Napoli in the decisive play-off which was played inL'Aquila, even if the permanence in the top division that time lasted the timespan of one season.

In the historic Acqua Acetosa field, CUS faced several rugby stars such as David Campese, John Kirwan and Naas Botha.

Notwithstanding with the disproportion between the forces in field, CUS Roma does not demerit and, according to many fans, played the most beautiful and spectacular game of the championship, thanks to the quality of its backs.

Many CUS players in those years were called up in the national team (Tinari, Pratichetti, Caranci, Salvati, De Biase, Ambrosio, to cite a few names).

The player that was a symbol of that generation was Stefano Barba, centre with outstanding attack abilities who took part at the 1987 Rugby World Cup and collected more than 30 caps for Italy.

In the early 1990s the university sports facilities in Tor di Quinto was inaguruated, where it stands "the biggest rugby field in Italy".

It could be the chance for a further step forward, but the rising financial restraints and a series of team vicissitudes marked the start of an era of gradual resizing of the CUS' ambitions.

Another split from a group of players and coaches gave birth to Unione Rugby Capitolina, weakening the CUS' organic in all the categories.
