How will Christian McCaffrey return impact 49ers offense?
The San Francisco 49ers have somehow managed to churn out a productive, efficient offense even without running back Christian McCaffrey.
Just because they've been able to churn out yards and points doesn't mean life hasn't been more difficult for the 49ers without the reigning Offensive Player of the Year. His return, which could be coming sooner rather than later, should make a couple of things much easier for the 49ers.
The first area McCaffrey should help is in the red zone. Last season the 49ers were the No. 1 red zone team in the NFL, scoring touchdowns on 67.2 percent of their red zone trips. This season without McCaffrey that number has plummeted to 44.4 percent.
His nose for the end zone as a runner alone will help, but his dual-threat skill set will open a ton of things up down near the end zone.
McCaffrey is a threat as a receiver, which defenses have to respect when he's out in a route. He can be moved around to help manipulate defenders and open up space for tight end George Kittle and wide receivers Deebo Samuel and Brandon Aiyuk.
Neither Samuel nor Kittle are great at creating separation, which becomes a significant problem in the confined spaces of the red zone. Having McCaffrey to occupy defenders could make life easier for the 49ers' other pass catchers.
That's the same way he can help elsewhere on the field where defenses have started clogging the middle of the field and taking away some of the space the 49ers offense has thrived in.
Quarterback Brock Purdy is still working the middle of the field, but the result of those throws isn't quite the same as it was over the last few seasons. 49ers pass catchers are making receptions in the middle of the field and not creating yards after the catch.
Last season Samuel racked up 8.7 yards-after-catch per reception. Kittle was at 7.3, while McCaffrey and RB Jordan Mason were both at 7.0 YAC/reception.
This year Samuel is down to 7.6 in that category. Mason is at 5.6 and Kittle's number has fallen all the way to 3.5.
Aiyuk's is largely unchanged.
Getting McCaffrey back where defenders have to vacate the middle of the field to account for him as a receiver should generate more space and more YAC opportunities for 49ers receivers.
We'll also likely see Purdy's completion rate tick up toward the 69.4 percent mark he landed on last season. This year as his downfield throws have skyrocketed, his completion rate has started falling. Part of the push downfield is likely due to how teams are defending the 49ers, but it stands to reason Purdy will take easier throws to McCaffrey instead of scrambling and creating out of structure the way he has so often this season.
It's unlikely the 49ers' offense will be an exact replica of last year when McCaffrey returns, but he should make some of the difficult things like red zone TDs and short-area throws much easier when he's finally back on the field.
