Gore is only the second opposing runner to gain more than 100 yards against the Chiefs this season. Miami’s Lamar Miller had 108 in a game two weeks ago.
But in total, the Chiefs are allowing an unhealthy 4.8 yards per carry. Against the 49ers, the Chiefs’ defensive front was often pushed backward.
According to ESPN Stats & Info, Gore gained just 20 yards after contact. He had 87 yards on his 18 carries, or 4.8 yards per attempt, before contact. The league average on Sunday was 2.7 yards before contact.
To some extent, the problems in the run defense are understandable. The Chiefs have played their past three games without four of their best run defenders: linebackers Derrick Johnson and Joe Mays, end Mike DeVito and safety Eric Berry.
Johnson and DeVito are out for the season, each with a ruptured Achilles tendon. Mays and Berry should return later in the season.
In the meantime, the Chiefs need to make the necessary adjustments. Their season depends on it.
"Nobody’s going to take it easy on us just because we’ve got some backups in our lineup," nose tackle Dontari Poe said. "If they’re in there, they’ve got to play like starters."
