Throughout the Sean McVay era, the Los Angeles Rams have primarily been an 11 personnel team. In 2017, the Rams ran 11 personnel on 83 percent of their offensive snaps. That has only increased since then as the Rams were in 11 personnel 93 percent of the time in 2023.
With such a heavy dose of 11 personnel, there is certainly reason to believe that the Rams and McVay should add more variance to the offense and add more 12 personnel packages. However, from the Rams standpoint, they are able to get away with so much 11 personnel because of how they use their wide receivers.
