URC has been enriched by South African infusion, but Leinster remain the team to beat

Retaining the United Rugby Championship (URC) title last season was a special achievement that will only be outdone if Leinster complete a three-peat next June before Leo Cullen rides off into the sunset.

The five-year history of this competition since the four South African franchises came aboard demonstrates that the URC is becoming more competitive. All manner of conditions and opposition await as teams juggle through nine interruptions for internationals and European games.
