Something I noticed last night, at least three times, the clock was stopped and the ref told us to go back and play it on the mark. Most times they barely moved from their position and play went on. If it happened to Penrith they'd get a penalty for slowing the ruck or some bullshit. Instead of penalisiing the Panthers for being in the ruck, it slowed play down and basically stuffed those sets.
Another thing that was apparent, was that on many occasions immediately after Penrith made an error, they got a penalty anyway, so the errors didn't cost them. Instead they actually gained from them. Now some of those penalties were probably justified, but it was a strange "coincidence " I noticed several times.
