Corum's 2025 splits tell the familiar backup story: mostly irrelevant through 12 weeks, then double-digit fantasy points in four of five games when Kyren Williams was limited down the stretch. When the Rams' scheme gives him carries, the efficiency numbers look remarkable–his success rate (97th percentile) and YBC/Att (97th percentile) both rank second in the NFL, and his run grade sits at the 89th percentile. The catch, as with Williams, is that the scheme is doing most of the work. Corum's elusive rating (15th percentile) and YAC/Att (17th percentile) are well below average, and his receiving profile is essentially nonexistent–he ranked dead last among qualified backs in both YPRR and route grade.
