12 of those 40 points were with 13 men on the field.
Then not having a lineout lead to the opposition having almost 70 percent territory because they couldn’t relieve pressure if they were awarded a penalty. The main line out option also went so the ability to put the opposition line out under pressure went. So that’s both the scrum and lineout essentially becoming uncontested for 1 team and not the other.
This leads to your 9-10-12 essentially having 1 option in attack, which allows the opposition to flatten their defensive line allowing for greater line speed.
I can teach you about the fatigue caused from clearing aspects of your forward rotation in the first half and the disadvantages of holding 3 props in your defensive line, especially in the second half when fatigue kicks in but not sure if some people really want to understand the 1 percenters that define the game. Because they see this as an opportunity to stick the knife in for some strange reason.
Look the reality is the Rebels weren’t really destined to win the game, you’d be a silly man for betting on them even when marginally up at half time. But it’s either ignorance on how the games played or a blind dislike for a team to truly believe at least half those 40 points couldn’t be attributed to the circumstances that conspired. If the reverse had happened and it was the Blues, the Rebels might not have run away with it like the Blues did (that’s just a gulf in class) but the Rebels would of also comfortably won.
