There are two important points to be made here. First, the general standard of refereeing in the CAS games this year (that I have seen) has been pretty poor. On Saturday I saw a referee (in an Opens game, but not the 1sts) penalise one team, then immediately penalise the other for not taking the tap on the mark. And the second Trinity/Aloysius game was marred by a really poor display.
But, you know what? We need them. And it's still the case that, no matter how bad they may be, they're always right. A lot of teams I've seen this year need to learn that lesson.
Incidentally, if I were refereeing these days, i'd be driven crazy by the number of players trying to do my job. At every breakdown, the scrum half on each team seems to think it's his job to explain to the ref why a penalty should be given. On Saturday, I saw (in the 1sts) a quick tap taken when most of the defending players were not back ten metres. The defending fullback ran up to just behind the defensive line yelling repeatedly "I'm onside, sir, I'm onside!", presumably thinking that this would distract the ref from all the players who were not. Refs shouldn't have to put up with nonsense like that.
