Should You Start Arizona Cardinals RBs Bam Knight or Michael Carter in Fantasy Football Week 12?
Arizona’s backfield chaos continues as injuries force yet another rotation through the depth chart. Emari Demercado’s ankle injury means it will be Bam Knight and Michael Carter in charge of the backfield this week. Can fantasy football managers trust either Cardinals runner in Week 12?

Bam Knight Fantasy Outlook
The Cardinals opened Trey Benson’s 21-day practice window earlier this week, but the sophomore participated in only three limited sessions and won’t return this soon after a two-month absence. This guarantees at least one more week of the backfield carousel featuring Knight as the primary option.
Knight’s usage took a significant hit last week against San Francisco due to extreme negative game script. The veteran back played just 40% of the snaps as the Cardinals fell into a massive hole, forcing Jacoby Brissett to throw 57 passes well into garbage time. Despite the limited involvement, Knight managed to deliver his best fantasy performance of the season.

The 14.5 fantasy points came from varied contributions across multiple phases. Knight carried the ball five times for 24 yards and found the end zone on the ground, then added four receptions for 21 yards through the air. Both the catch total and receiving yardage represented season-high marks for a back who had been relegated almost exclusively to early-down work.
Knight should retain his role as the early-down and goal-line back moving forward. He has led the Cardinals’ backfield in red-zone rushing attempts over recent weeks, giving him legitimate touchdown upside in favorable game scripts. The efficiency remains concerning, as Knight owns just a 2.1% explosive run rate and averages only 1.60 yards after contact per attempt.
Michael Carter Fantasy Outlook
Carter had been completely phased out of Arizona’s offense before injuries to Knight and then Demercado forced him into action each of the past two weeks. The veteran has operated in passing situations almost exclusively, creating a defined but limited role.
Carter caught five passes on seven targets for 22 yards against the 49ers. The volume provides evidence of his designated role when Arizona falls into obvious throwing situations. However, the complete absence of rushing attempts (two total) and minimal yardage per reception severely cap his fantasy ceiling.

The Cardinals should maintain more competitive game scripts moving forward after back-to-back blowout losses. Arizona faces Jacksonville as home underdogs, but the 3-point spread suggests a contest that remains within reach throughout. Brissett won’t attempt 57 passes again.
Fantasy managers desperate enough to consider Carter need realistic expectations about his upside. His ceiling sits at 8-10 fantasy points in an absolute best-case scenario, with the more probable outcome falling between 3-5 points.
Carter functions purely as a receiving specialist without access to rushing volume or goal-line opportunities, eliminating multiple paths to fantasy scoring.
Should You Start Knight or Carter This Week?
Jacksonville presents a challenging defensive matchup for Arizona’s running backs. The Jaguars allow the eighth-fewest schedule-adjusted fantasy points per game to running backs, ranking among the league’s better units against the position.
The game environment projects as competitive despite Arizona’s recent struggles. Jacksonville enters riding momentum from a dominant victory over the Chargers, making them dangerous road favorites. However, Arizona has demonstrated an ability to keep games close at home despite their 1-4 record at State Farm Stadium.
Knight represents the superior fantasy option because of his touchdown potential. His goal-line role provides legitimate scoring chances if Arizona generates red-zone opportunities. The early-down work also guarantees him volume regardless of game script, though negative scenarios would reduce his overall opportunity count significantly.
Carter belongs on fantasy benches in all but the deepest leagues. His ceiling remains capped by his one-dimensional role and lack of big-play ability.
Managers forced to start Carter due to roster constraints should view him as a desperation Flex whose floor sits dangerously close to zero. Knight profiles as a low-end RB3 with touchdown-dependent upside, while Carter offers minimal fantasy relevance even in favorable game scripts.
