Who Should I Start? Christian McCaffrey or Marlon Mack

Friday, October 2, 11:44 PM

San Francisco 49ers running back Christian McCaffrey is in line for a productive Week 4 when he squares off against the Denver Broncos. So far in 2026, Denver has given up the third-most rushing yards, has the highest EPA allowed per run, and has the most missed tackles in the league. The Broncos defense will also be missing linebacker Dondrea Tillman (hamstring). This makes for an inviting matchup for McCaffrey, who owns the league's fifth-best rushing success rate and the highest average rushing yards before contact among starting running backs. As usual, McCaffrey can be expected to be one of quarterback Brock Purdy's favorite targets. And with Mike Evans (ribs) questionable and expected to be a game-time decision on Sunday, McCaffrey could see his receiving work increase. The Broncos gave up six catches for 70 yards to Kyren Williams last week. McCaffrey is projected as the overall RB6 in Week 4.
