Agree about Joubert, I may have been disappointing he was reffing but he didn't do a lot wrong. You can argue about his not giving players chances to get out but he applied the law. The onus in on the tackler to try to get away and not the players joining the ruck to let them roll away.
As for advantage its a rule that depends on the ref some let teams have a lot of it, others not so much. In my playing youth I was always taught that advantage lasted for up to 10m beyond where the penalty would be given.
On the whole we played a good game. Thought Warbs was superb, he seems to have benefited from his lesser playing time and looks a yard quicker. Ball and AWJ played well, both carrying and tackling well. Webb got the try but those 2 killer intercepts somewhat tarnished his overall display. Today was the sort of game that you wished Stephen Jones or Neil Jenkins were playing now, they knew how to manage a game, Biggar and Patchell are attacking 10's and Preistlnd isnt playing well. Lets hope this Anscombe chap shows he can manage a game
