Four Factors: Saints vs. Bills This week’s survivor league favorite is the Buffalo Bills. Vegas has them as massive 15.5-point favorites against the Saints in a noon kickoff Sunday on Channel 4. The Four Factors for New Orleans: Offense: The Saints must finally push the ball deep. They rank last in explosive plays. Defense: Pressure is missing. They’re bottom-five in QB hits, and Josh Allen won’t be easy. Special Teams: Flat-out worst in the league through three weeks. Coverage, field goals, blocks — all issues. Coaching: New HC Kellen Moore faces a huge test. This is a rebuild, but discipline and focus must improve now. The Saints don’t have to win Sunday in Buffalo — but they have to look better.
