Negative signalUsage
RB6 with declining usage; rush attempts down 31% YoY, receptions down 33%.
RB6 ranking; usage has decreased significantly year-over-year—rush attempts down from 18.3 per game last year to 12.5 this year; receptions down from 6 to 4 per game; still averaging north of 16 combined carries and targets per game with upside for 20+ touches; efficiency improved to 4.4 yards per carry, but Mike McDonald's defense has held CMC to 11.7 and 12.4 PPR points in the two most recent matchups, making this a less favorable spot despite his overall tier ranking.
