Rosas posted 36 against North Melbourne in a tight 8-point win — below his 50 BE and miles from his 84 season average. This was a genuine contest, not a blowout, so context doesn't explain the output. After the 7-goal R8 masterclass the cash gen was flying at $8,154/rd; this will slam the brakes on that. His role at Sydney is locked and one poor game doesn't kill the season narrative, but watch for follow-through before adding.
