Trouble spots for QB pressure

Steve Palazzolo of Pro Football Focus offers a breakdown of AFC South quarterbacks under pressure.

The Indianapolis Colts and Tennessee Titans added linemen at what was a trouble spot for their QBs.

A team by team look at PFF's findings.

Texans: Matt Schaub’s numbers over five years show he’s capable of posting very strong numbers when his protection keeps him unbothered. Palazzolo notes that Schaub’s 101.3 PFF grade on plays where he has not faced pressure puts him eighth in the NFL and ahead of the two quarterbacks who won the two most recent Super Bowls, Eli Manning and Joe Flacco.

Schaub’s biggest pressure trouble comes when defenders come from left tackle. That shows us why Duane Brown is such an important piece of the Texans line.

Colts: Andrew Luck’s got just one season of data, but pressure from right tackle hurt his play the most as he scored minus-3.2 in those 49 snaps. General manager Ryan Grigson responded by signing free-agent right tackle Gosder Cherilus.

Jaguars: Left guard was a problem position for the Jaguars last year, where Will Rackley was lost to a preseason injury and the team used Eben Britton, Mike Brewster, Austin Pasztor and even Herb Taylor in the spot. Blaine Gabbert was a minus-4.8 when pressured from that position.

Chad Henne had more problems with pressure off the edges -- with a minus-3.2 from left tackle and a minus-3.2 from right tackle, where he faced twice as much of a rush to deal with.

A healthy Rackley and No. 2 overall draft pick Luke Joeckel, who will play right tackle, should do a lot to help in both areas. But note that Rackley earned a minus-18.4 in pass protection in 2011.

Titans: Locker was hurt by pressure over right guard, situations in which PFF scored him minus-3.5 in 23 qualifying plays. Leroy Harris was lost there after half a season, then Deuce Lutui played the rest of the way. Now Locker and the Titans will enjoy a major upgrade with No. 10 overall pick Chance Warmack plugged into the spot.
