PASS DEFENSE SPECIAL TEAMS

The Ravens covered and tackled well in limiting Steelers QBBen Roethlisberger to 266 yards on 51 attempts. But they’re thin at cornerback, especially if they have to play without Jimmy Smith, who left the Pittsburgh loss with a groin injury. CB Marlon Humphrey forced two fumbles and defended two passes against the Steelers and appears on track for another Pro Bowl selection.

Kicker Justin Tucker has missed just once (from 61 yards) this season. Punter Sam Koch ranks sixth in the league with a net average of 43.2 yards and has put

20 of 44 inside the opponent’s 20-yard line. The Ravens have accumulated 645 yards on returns compared with 430 for their opponents, and Tucker is sixth in the league with 43 touchbacks on kickoffs.

Dallas hasn’t defended the pass well either, allowing opposing quarterbacks to average 6.7 yards per attempt. The Cowboys blitz relatively infrequently and rank middle of the pack in pressures and sacks. Defensive ends Lawrence and Aldon Smith are their most productive pass rushers with 9½ sacks and 19 quarterback hits between them. Rookie Trevon Diggs, the team’s best cornerback, is on injured reserve.

EDGE

Kicker Greg Zuerlein has made 21 of 24 field-goal attempts, with all three of his misses coming from beyond 50 yards, but he has missed three extra-point tries. The Cowboys switched punters after Week 8, going with Hunter Niswander, who’s performed well in a limited sample with a 44.7-yard net average. They’ve excelled on returns, with 781 combined yards compared with 442 for their opponents.
