It’s never too early to start preparing for next season, and for PFF, that means looking at ways to improve PFF Premium Stats. One way we’re looking to enhance the experience is by introducing more data into the mix.
Over the last couple of weeks, we have presented a new metric we’ve coined “Lockdown Percentage,” which identifies The NFL's best defenders at preventing separation in coverage.
