Every week, reporter Jon Meoli will serve up five stats you should know heading into that week's Ravens game. This week's stats, prepared ahead of Sunday's trip to NRG Stadium for a grudge match against the Houston Texans, focus on the Ravens' ball security, success on the ground, and yet another measure of quarterback Joe Flacco's success this year.
17 – The Ravens have been among the league's best in not turning the ball over this season, and they will have to be again against a Houston defense that ranks first in the league with 31 takeaways, and a league-high 110 points off takeaways. Quarterback Joe Flacco has thrown just one interception in his last five games, and a pair of fumbles by fullback Kyle Juszczyk are the only other turnovers in that span. Ball security will be at a premium, especially in the red zone, where the Texans have forced 11 turnovers.
3.0 – Last Sunday, running back Justin Forsett averaged 3 yards per carry, a full yard lower than his previous season-low in that category. That simply can't happen again as the Ravens look for a better offensive performance than last week's display against the Jacksonville Jaguars. For a player who has averaged more than 5 yards per carry in eight of 15 games this year, it's not out of the question that Forsett just ran into a tough defense. But if he's down around 3 yards per carry again, and with fellow running back Lorenzo Taliaferro no longer around to spell him, it could represent a troubling trend for the Ravens' once-vaunted rushing attack.
33 – Right tackle Rick Wagner is in the spotlight this week because of his matchup with fellow Wisconsin Badger and wrecking ball J.J. Watt, but his run blocking deserves praise as well. The Ravens' 33 runs of 10 or more yards to the right side is the most of any team to any part of the line, according to NFL data. Wagner and right guard Marshal Yanda will be tested with Watt and Houston's front seven, but to this point, the Ravens have had a ton of success running behind the duo.
74.3 – ESPN created its own quarterback rating, QBR, and Flacco's 74.3 mark is sixth overall, but really is fifth when considering Carolina Panthers backup quarterback Derek Anderson barely qualifies and leads the league because of it. There are plenty of different ways to show how good of a season Flacco is having, and this is just another one. And though wide receiver Torrey Smith gets credit for drawing pass interferences, Flacco is tops in the league with 13 pass interference penalties drawn for 275 yards. A few of those being completions instead could help him get over the elusive 4,000-yard mark.
73.3 – The Ravens only allow points on trips inside the red zone 73.3 percent of the time, the best rate in the NFL. Their touchdown percentage of 46.7 is fifth-best in the league, but the Ravens' pass rush and ball-hawking run defense inside the red zone both push teams out of the red zone and take the ball away before they get scoring opportunities. That could come in handy against whichever untested quarterback Houston runs out Sunday.
