Yahoo News : Six NFL quarterbacks enter Week 11 with perfect play

This year, the National Football League has added "Playtime Percentage" to the Gamebooks that are found in the "Game Centers"* at NFL.com. That information is not always updated on the public end, but it is updated the morning after each game on the NFL Media site. I've been tracking that data throughout the season for Shutdown Corner, and here are a few observations through Week 10: On Monday night the Pittsburgh Steelers lost quarterback Ben Roethlisberger to a right shoulder injury, specifically a sprained sternoclavicular joint injury that has the two-time Pro Bowler questionable for this upcoming Sunday night game against the Baltimore Ravens. Roethlisberger had been one of a steadily decreasing number of players who had played in 100 percent of his team's offensive or defensive plays this season, but his perfect playing-time season came to an end when he was sacked by Kansas City Chiefs linebacker Justin Houston with 14 minutes remaining in the third quarter. Philadelphia Eagles quarterback Michael Vick had also been on that list entering Week 10, but his concussion in the second quarter of Sunday's 38-23 loss to the Dallas Cowboys put an end to that somewhat surprising display of longevity from Vick, who couldn't make it through a 2012 preseason game without suffering an injury. Currently, six NFL quarterbacks have taken 100 percent of his team's offensive snaps thi sseason. Three of the quarterbacks are rookies, including No. 1 overall pick Andrew Luck of the Indianapolis Colts and No. 22 overall pick Brandon Weeden of the Cleveland Browns. The third rookie passer with 100 percent playing-time this season is Russell Wilson, who was selected by the Seattle Seahawks in the third round (No. 75 overall). The three veteran quarterbacks with 100 percent playing-time entering Week 11 are Drew Brees of the New Orleans Saints, Philip Rivers of the San Diego Chargers and Tampa Bay Buccaneers quarterback Josh Freeman. Skill-Position Playing-Time Percentages Sixty-one players on offense have perfect playing-time percentages —six quarterbacks and 61 offensive linemen. Here's a look at the Top 5 playing-time percentages (not raw snap counts) among the skill-position players in the National Football League through Week 10: Running Backs LeSean McCoy, Philadelphia Eagles — 81.2 percent Ray Rice, Baltimore Ravens — 80.76 percent Chris Johnson, Tennessee Titans — 80.49 percent Doug Martin, Tampa Bay Buccaneers — 74.73 percent Arian Foster, Houston Texans — 73.8 percent Other running backs with playing-time percentages over 70 percent: Adrian Peterson (72.37 percent), Marshawn Lynch (70.6 percent) and Frank Gore (70.04 percent).
