Petracca was an option for those going him and beat him soundly.
Danger and Rowell smashed him but anyone who captained them probably was more lucky that good.
Neale and Miller both very strong options that beat him.
This week Cripps has already beaten him soundly and given that the Cripps/Rowell combination would almost certainly be the most common reason that people didn't start Macrae it's a very relevant one to beat him.
From your wording I get the opinion that you think leaking means significant points, for mine a leak is more a small thing than large, so probably shapes things a bit as well!
Either way, for me personally not starting Macrae has been a big win through 10 games!
Long season though and one of the major positives of Macrae is that you can have confidence that he's still producing in round 22! Albeit I'd be hoping he's been producing in my side for something like 16 of those rounds
