49ers May Have Found Christian McCaffrey's New Strength

He's at his best when rushing between the tackles. In the past, McCaffrey was very effective on outside runs, but the stats are proving that inside runs are his new strength.

Seven of McCaffrey's 10 carries (70.0%) against the Rams went between the tackles, the third-highest inside run rate in a game as a member of the 49ers, per Next Gen Stats.

He accumulated 54 yards on those seven carries (7.7 yards per carry), with six of these runs (85.7%) accompanied by pre-snap motion. Inside runs are his bread-and-butter now.

Stretch runs used to be sharp for him. He had the vision and the fluid one-cut ability to get upfield to the second level. However, his speed has diminished a bit.

Widening out on outside runs, as opposed to running straight inside, demands greater speed. Last year, McCaffrey was extremely ineffective on outside runs.

Poor blocking played a significant role in that, but it's clear he's better running north than east or west. This is how the 49ers should use McCaffrey moving forward.

And it looks like they will. 70% of his carries were inside runs, and they generated immense success. There's no reason for the 49ers to get away from that.

Just like there's no reason to give him more carries than Black. It worked. Everything worked with McCaffrey. They came up with the perfect approach with him.

On 28 of Black's snaps against the Rams, 26 of them came on first or second down. It's clear the 49ers want him involved early and often to keep McCaffrey fresh.

That's what led McCaffrey to explode on a few runs in the second half. Reducing his workload and running him mostly inside is what will keep him great.

They have the proof after Week 1, and it shouldn't change in Week 2 against the Dolphins.
