Spot on warhorse. On another day, uni will be pinged out of the contest if they dont learn to support their own body weight over the ball when going the jackal, and if they continue to hold on after making a tackle. Bewildering rules today, but uni deserved to win. They mostly won the contests all day. With so much to play for, it remains a mystery to me why souths started so poorly. 2 scrum penalties on their own feed, 3 out of their throws in the first 4 lineouts were stuffed up, (and I think 7 out of the first 10, I think)). A bunch of other penalties, meant no ball or field position and 21 - 0 after 15 mins. That is where the match was lost, and the ref had nothing to do with that. Sad days.
You just have to be physically and mentally ready to go. Just call simple lineouts early, bash it up and belt a few bodies about until the game settles down . Uni did, magpies didn't. Prem grade players should not need to be told.
