With McCaffrey placed on injured reserve, the Minnesota Vikings could play the 49ers more straight-up on third downs Sunday in their 23-17 victory at U.S. Bank Stadium. "I think just being able to drop back in zone and not having to put two guys on a running back coming out of the backfield like Christian," quarterback Brock Purdy answered when asked how teams can play the 49ers differently when their top back is not on the field. McCaffrey is a unique player due to his prowess as both a runner and receiver. Last year, he was named NFL Offensive Player of the Year after rushing for 1,459 yards and 14 touchdowns and catching 67 passes for 564 yards and seven scores. Mason got his second start with McCaffrey out, and he came through with his second 100-yard performance. Mason rushed for 100 yards and a touchdown on 20 attempts. JP puts the 49ers within a score ...
