He's a one dimensional north/south runner who got stuck behind an extremely inconsistent and honestly bad offensive line.
Alvin Kamara, a far superior running back, had just 3.7ypc in 2021, 4.0 in 2022, and 3.9 in 2023. His 3.86ypc average over the last three years is more than a full yard less than his 5.1ypc average his first four years in the league. His career ypc average has actually dipped lower than Mark Ingram's, who retired with 4.46ypc. Kamara currently sits at 4.43ypc.
