The San Francisco 49ers' 5-0 start and two-game division lead have driven their 58.5% implied probability as NFC West favorites, fueled by a dominant recent 32-29 road win over the Seahawks that showcased opportunistic defense and timely scoring despite offensive inefficiencies. Seattle's 3-2 mark and recent loss have tempered expectations for a repeat title, leaving them at 19.5% amid a tougher upcoming schedule. The Los Angeles Rams sit at 2-3 with limited early momentum, reflected in their 21.0% share, while the Arizona Cardinals' 1-4 record has all but eliminated them at 1.6%. Trader consensus emphasizes the 49ers' early form and head-to-head edge in a competitive division.
