Match analysis

San Francisco is 2-0 after scoring 62 points in two games, and Brock Purdy's 80.4% completion rate with five touchdowns makes the early efficiency difficult to dismiss. Christian McCaffrey adds two rushing scores, while Arizona fell 31-7 to Seattle and averages 16.5 points. Jacoby Brissett has been steady, but the Cardinals' 272 yards per game leave little room for negative plays against a favorite laying more than a touchdown.

The official Wednesday sheet differs sharply from the ZIP's final-sounding designations. Arizona listed Roy Lopez, Max Melton, Isaac Seumalo, Josh Sweat and Dadrion Taylor-Demerson as DNP; Garrett Williams was limited, not OUT. San Francisco's Nick Bosa, Mike Evans, Dre Greenlaw, Christian McCaffrey, Trent Williams and several others were DNP. Those statuses may include rest, and no Sunday game designation had been issued, so the projected unit remains conditional.

San Francisco swept the 2025 meetings 16-15 at Levi's Stadium and 41-22 in Arizona. That range is a useful reminder for 49ers -8.5: the matchup can become a one-possession divisional grind or break open when Arizona cannot survive the 49ers' motion and yards after catch. Purdy's fast processing and McCaffrey's alignment flexibility favor the favorite; a heavy DNP list and Arizona's +2 turnover differential are the reasons the margin is demanding.
