I went and rewatched the rd 4 game yesterday before heading to Ctown. I'd argue that win had more to do with getting the warriors at a good time than us being brilliant. The same issues we've had all year (shit red zone attack, etc) were all present in that game too. We were just lucky that the warriors were going through the Metcalf thing that clearly unsettled them for a couple of weeks. In the rd 4 game, they were actually physically dominant for the majority of that game and their pack actually outran ours that night.
We won because of long-range tries that went down the Metcalf edge all game. If the warriors didn't parachute Metcalf into their squad for that game and kept going with Harris-Tavita, that game probably ends up like the score we had last night. There is a reason why we've only beaten the warriors once in 6 years. We have always struggled to handle their physicality and power up front.
