The one knock that I would have with James Cook in comparison to the other running backs inside of this tier, we don't have the same type of ceiling. Where Cook has at most seen 17 and a half fantasy points per game in his NFL career 4 years in, we're not necessarily expecting the running back to get better at 27
STACKED’s take
Negative signalProjection
Cook has a ceiling limitation compared to other tier peers; he's maxed out at 17.5 PPG in his four-year career and isn't expected to improve at age 27.
