Now, all eyes turn to Sunday, where Philadelphia and Buffalo host the weekend's final two matchups. The Philadelphia Eagles welcomed the Los Angeles Rams to a wintry mix at Lincoln Financial Field for an intense NFC showdown, while the Buffalo Bills take on the Baltimore Ravens in a clash of AFC powerhouses.

But a secret weapon has emerged at the right time for Buffalo.  The extra offensive lineman.  Through two games in the playoffs, the Bills have utilized six (or more) offensive linemen on 28.5% of their 80 rush attempts.
