STACKED’s take
Kenneth Walker leads league in fantasy points; elite efficiency independent of O-line.
Kenneth Walker is the best running back in football through two weeks, leading the league in fantasy points scored and ranked RB4 for Week 3. He is the best individual performer at the position by a significant margin, ranking in the top right corner on yards after contact per carry and tackles avoided per carry charts—well ahead of other elite backs. Walker is operating at an elite level independent of offensive line quality; Ian Hartitz notes the Chiefs' running backs collectively ranked dead last in these metrics last season but now rank easily first in both, a testament to Walker's individual excellence. He ranks #1 in the NFL in percentage of carries gaining 3+ yards after contact, demonstrating elite ability to consistently move the pile and gain hard-fought yards independent of big runs. With an 82% snap rate in Week 2, he has a confirmed workhorse role. He ranks RB3 in cool rate efficiency among RBs with 14+ opportunities and leads all RBs in raw cool counts with 34, well ahead of second place Jamir Gibbs at 25.
