How are Bears running backs faring in the eyes of advanced stats?

The Chicago Bears’ ground game looks dominant in basic numbers through three weeks, but advanced stats suggest it’s been more uneven than the league-leading totals imply. New Orleans isn’t involved; it’s Chicago. The Bears have 553 rushing yards and 5.3 yards per carry, leading the NFL, yet 291 of those rushing yards came in Week 1 against the Carolina Panthers, when D’Andre Swift produced 124 yards on 18 carries and Kyle Monangai averaged 10 yards on 10 attempts (100). In the two following games, Chicago totaled 134 and 128 rushing yards, with Swift at 2.8 YPC vs. Minnesota and Monangai improving to 4.7. EPA and yards-over-expected further favor Monangai: +0.08 EPA vs. -0.01 for Swift.
