San Francisco enters Sunday riding high after back-to-back double-digit blowouts against the Rams (27-7) in Melbourne and the Miami Dolphins (35-13) in their home opener. The 49ers’ offense has been controlling game scripts from start to finish. Arizona, meanwhile, arrives hungry for redemption following a frustrating 31-7 loss to the Seattle Seahawks, after previously opening their season with an impressive 26-14 victory over the Los Angeles Chargers.
