The Ravens' running back has emerged as one of the top runners in the NFL. He ranks fifth in the NFL with 903 rushing yards and seven touchdowns. He's on pace to finish the season with 1,313 yards. He's averaging 5.8 yards per carry, thriving in offensive coordinator Gary Kubiak's zone-blocking system. Forsett has been patient, elusive and determined, breaking several tackles. The Chargers run defense has struggled a bit, allowing 120.6 rushing yards per game since the seventh week of the regular season. Over the past two games against the Oakland Raiders and the St. Louis Rams, the Chargers have held opponents to 89 rushing yards per game as they've gotten back Melvin Ingram and Manti Te'o. Overall, though, this hasn't been a very stout defense as the Chargers have missed plenty of tackles. They rank 15th in the NFL in rushing defense, allowing 108.8 rushing yards per game. The Ravens have worn down defenses lately in the fourth quarter, when Forsett appears to get stronger.
