RB17 vs. RB14 ECR; Blake Corum's 50/50 split limits ceiling.

JJ Zachariason ranks Kyren Williams as RB17 versus ECR's RB14 and has shifted to an against-drafting stance primarily due to Blake Corum's role expansion. Corum averaged 5.1 yards per carry and 10.5 carries per game in the second half of last season, with team reports trending toward a 50/50 early-down split this season. Williams is not efficient enough to dominate with limited touches and relies on volume; splitting early-down work with Corum while already facing a low team pass-target rate to running backs (Rams throw to RBs at the lowest rate in the league) creates floor risk. While Williams should retain goal-line work and the Rams have discussed increasing his third-down usage, Zachariason worries about touch distribution: if Williams splits early-down work with other backs while also increasing third-down involvement, his total touches could decline significantly. Zachariason's core concern is that Williams needs approximately 15 touchdowns to justify his draft position and avoid being a regret; 10-12 touchdowns with fewer carries and receptions won't overcome the opportunity cost. He fades Williams in favor of David Montgomery three rounds later, who offers similar production at lower ADP.
