SavvyPlays Tip — Lean

01Port Adelaide by 9

Port Adelaide’s R20 upset of Brisbane (by 28 at the Gabba) was one of the results of the season. Whether that represents genuine improvement or a one-off is the question. Their 6–12 season record and 3–7 home record say one-off.

But GWS are 1–8 away from home — the worst travelling record in the competition. The H2H favours Port 3–2. 22/27 models tip Port at 59.1% with +8.9 margin. We’re at +9. Lean because Port’s home record is poor, but GWS on the road are even worse.
