The wiki doesn't have a specific training camp report detailing the ratio of zone runs to play-action, but it makes crystal clear that Klint Kubiak's offense is built on both — they're two sides of the same coin.
From the Kubiak page: "Outside-zone running game, play-action passing, condensed splits. Expect a heavy run identity with under-center looks." The OC Andrew Janocko's page echoes that: the offense is built around "Shanahan-style outside-zone running game with play-action passing" (from the Andrew Janocko page).
Here's what that means for fantasy:
- Outside zone is the engine. The Raiders signed Tyler Linderbaum to the richest interior OL deal ever ($81M) specifically to unlock zone runs for Ashton Jeanty. Kubiak's Seattle offense was "very run heavy" per Sal Vetri — they let Kenneth Walker walk in free agency and leaned into the ground game ().
- Play-action is the payoff. The condensed splits and under-center looks are designed to freeze safeties, then attack with play-action off that same zone look. Brock Bowers and Jalen Nailor should benefit heavily.
So the short answer: both are featured equally, because play-action depends on the zone run being a credible threat. No training camp report has suggested one is being emphasized at the expense of the other — it's a fully integrated Shanahan system.
