I thought the Broncos got the rub of the green with the refs vs. the Warriors, particularly around the ruck (other than the very obvious forward pass). I think they were playing silly buggers slowing them down intentionally and for way too long and too often. If they get the same latitude vs. the Panthers, they will win. I watch the Panthers and how they address the ruck and they are just super fit and race back onside etc. if they don't get the advantage with the tackle. It will be won in the ruck, the forwards, the arm wrestle, penalties and mistakes.
