Rohit Ponnaiya advised playing Under 5.5 receptions on Christian McCaffrey against Arizona. The Cardinals allow just 3.9 catches per game to running backs (eighth-fewest). More importantly, quarterback Brock Purdy and wideout Ricky Pearsall return after six-week absences. Ponnaiya noted that Purdy attacks downfield more often than backup Mac Jones, and Pearsall ranks 12th in yards per route run, joining Jauan Jennings, George Kittle, and Kendrick Bourne to give San Francisco a deep arsenal. With so many mouths to feed, Ponnaiya expects McCaffrey’s target share to dip, making six catches an uphill climb.
