NFC West: Darren Howard

Justin SmithAP Photo/Paul SakumThe 49ers' Justin Smith has collected 8.5 of his 21.5 sacks after the third quarter since 2008.

The try-hard guy, long revered by NFL fans for overcoming physical limitations with all-out effort, has not been universally loved.

Established veterans with a feel for how to practice during long, demanding regular seasons can become resentful when the try-hard guy's misplaced fury produces unwanted collisions.

So, for the sake of clarity, the try-hard guy is excused from this conversation about pass-rushers so relentless, they wear down opponents over the course of a game.

We're talking about players with enough talent to command significant playing time, many as high draft choices or big-ticket free agents. We're talking about the San Francisco 49ers' Justin Smith, one of two NFC West players to receive votes in ESPN.com's Power Rankings for defensive players. Patrick Willis was the other.

"Justin Smith is a relentless player who wears down opponents by coming after them each and every play," BigBrad184 wrote in response to this item Wednesday morning. "I don't have any stats to back this up, but it seems like he often gets many of his sacks in the fourth quarter because of the fatigue he causes to offensive lineman."

Interesting thought.

"Maybe breaking out Smith's sacks by quarter over the past few years is a project for Sando," BigBrad184 concluded.

Done deal. John Fisher of ESPN Stats & Information responded to my request for the statistical evidence BigBrad184 was seeking. Smith does rank among the NFL leaders for fourth-quarter sacks in recent seasons, but two other NFC West players, including one of Smith's teammates, rank higher on the list.

More on the results in a bit. First, a look at the methodology.

Fisher provided a file with quarter-by-quarter sack totals for every player since 2001. I filtered the information to consider:

  • The last three seasons. There was no sense comparing totals for eight-year veterans against players entering the league more recently. At the same time, three seasons was long enough to pile up adequate numbers.
  • Players with at least 10 sacks. This reduced qualifying players from 668 to 99, a more manageable number featuring more "name" players.
  • Late-game production. I then divided the remaining 99 players' fourth-quarter and overtime sack totals by their total sacks, producing percentages that might tell us which players tend to wear down opponents.

The 49ers' Smith collected 8.5 of his 21.5 sacks in fourth quarters or overtimes since 2008. That worked out to 39.5 percent, which ranked 22nd among the 99 qualifying players.

Philadelphia's Darren Howard, who did not play in 2010, led the way with 75.8 percent of his sacks (11.5 of 16.5) after the third quarter. He was on the Eagles' roster for two of the three seasons in question and never played even half the defensive snaps in either year. But he was highly effective as a situational player, at least when measured by sack totals. Only Jared Allen (15) and Joey Porter (14) had more total sacks after the first three quarters.

There was no way to tell whether players with higher late-game sack percentages had more or better late-game opportunities for reasons unrelated to being relentless. Players operating within superior schemes or alongside better teammates certainly benefited. Overall, players collected more sacks in second and fourth quarters, no surprise given that teams attempted 6,130 additional passes during those quarters over the past three seasons, a likely reflection of two-minute situations.

The San Francisco 49ers' Parys Haralson (52.9 percent) and the St. Louis Rams' Chris Long (48.6 percent) ranked highest in fourth-quarter sack percentage among current NFC West players with at least 10 sacks over the past three seasons. Haralson was seventh in the league. Long was ninth. Former 49er Tully Banta-Cain was 10th (48.4 percent), while Arizona's Joey Porter (44.4 percent), St. Louis' Fred Robbins (44.4 percent), ex-Seahawk Lawrence Jackson (44.0 percent) and current Seahawk Chris Clemons (41.0 percent) ranked among the top 20.

Were these guys merely slow starters? Were they strong finishers? Did they wear down opponents over the course of games? The numbers do not answer those questions definitively, but they provide a starting point for discussion.

I was also interested in seeing which players collected a disproportionate number of sacks earlier in games. They were, at best, tone setters. At worst, they failed to finish or failed to adequately wear down opponents. The previous disclaimers applied to them as well.

As the chart below shows, three of the 10 qualifying players with the lowest percentages of late-game sacks have NFC West roots.

Arizona's Calais Campbell has 5.5 of his 13 sacks in first quarters, but only one in fourth quarters or overtimes. The 49ers' Manny Lawson collected 11 of his 12 sacks in the first three quarters. Darryl Tapp, traded from Seattle to Philadelphia in the deal for Clemons, has 4.5 sacks in each of the first two quarters, but only two in second halves (one after the third quarter).

A few other observations with an eye toward the NFC West:

  • Porter (six) and Campbell (5.5) rank among the top seven in most first-quarter sacks. The 49ers' Smith is right behind with five.
  • Arizona's Darnell Dockett has nine of his 16 sacks in second quarters. Eight players have more second-quarter sacks over the past three seasons, but all are edge-rusher types. Dockett plays end in a 3-4 scheme.
  • Pittsburgh's James Harrison and LaMarr Woodley are a third-quarter nightmare for opposing quarterbacks. Harrison leads the NFL with 15.5 sacks in third quarters. Woodley is second with 12. Former Cardinal Calvin Pace ranks in the top 10 with 7.5.
  • Porter and Allen are tied for the most fourth-quarter sacks in the NFL over the past three seasons. Each has 14 (Allen also had one in overtime). DeMarcus Ware and Robert Mathis are next with 13.5, followed by Dwight Freeney and Julius Peppers with 12.5.

Back to the original question: Is the 49ers' Smith a relentless player who wears down opponents, producing fourth-quarter payoffs?

He might be, but he produces well enough across all quarters to transcend the try-hard label and probably even the relentless label as well. He's a beast.

Matt Maiocco of the Santa Rosa Press-Democrat says Parys Haralson could "easily" finish the season with 10 or more sacks if he could stay healthy. Twelve NFL players reached double-digit sacks last season: Demarcus Ware (20), Joey Porter (17.5), John Abraham (16.5), James Harrison (16), Jared Allen (14.5), Julius Peppers (14.5), Justin Tuck (12), Mario Williams (12), Robert Mathis (11.5), LaMarr Woodley (11.5), Dwight Freeney (10.5) and Darren Howard (10). Note that none of the 12 played in the NFC West.

Also from Maiocco: Rookie Glen Coffee has stepped up in earning the No. 2 job behind Frank Gore.

The 49ers' Web site runs a fan question-and-answer transcript involving Parys Haralson. Haralson: "Basically we simplified our scheme and he let us do what we do best. He let guys go after the quarterback and let us play football."

John Crumpacker of the San Francisco Chronicle profiles 49ers running backs coach Tom Rathman. Crumpacker: "Although he loves his job, Rathman said he's no NFL lifer in the making. He said he'd like to put in 15 years as an assistant coach, get his pension, and retire to enjoy life sans air horns, blocking sleds and film study."

Also from Crumpacker: Rathman's recollections about lining up incorrectly on the winning play against the Bengals in Super Bowl XXIII.

Mark Emmons of the San Jose Mercury News checks in with 49ers fullback Brit Miller, who has caught the 49ers' attention as a converted linebacker.

Kent Somers of the Arizona Republic says it's unclear why Larry Fitzgerald restructured his contract with the Cardinals. The usual reason -- to clear cap space in the short term -- does not appear to be the motivation.

Also from Somers: Anquan Boldin thinks the Cardinals' approach to training camp helped cut down on injuries.

Darren Urban of azcardinals.com says Early Doucet made a spectacular one-handed reception upon returning from a shoulder injury.

Also from Urban: Cardinals coach Ken Whisenhunt would have liked a longer training camp. Urban: "The NFL calendar began later and NAU begins at the same time, forcing the Cards to leave after just 3.5 weeks."

Art Thiel of seattlepi,com says Seahawks rookie Max Unger impressed during the team's exhibition opener.

Danny O'Neil of the Seattle Times says the Seahawk's offensive linemen are sporting mohawks.

Steve Kelley of the Seattle Times considers whether Walter Jones' latest knee surgery marks the beginning of the end for Seattle's best offensive lineman.

Eric D. Williams of the Tacoma News Tribune thinks Julius Jones and Aaron Curry will be questionable for the Seahawks' second exhibition game.

Also from Williams: Sean Locklear will get extended work at left tackle for the Seahawks against Denver. The team needs him in that capacity while Jones recovers. This line would be in trouble if something happened to Locklear.

Clare Farnsworth of seahawks.com says the Seahawks found their first training camp under Jim Mora to be a grind. Farnsworth: "This camp was shorter, even if it didn't seem that way to the players. The Seahawks have traditionally broken camp before the third preseason game. This year, with Mora contorting tradition at seemingly every turn, camp broke before the second preseason game. But the gap was bridged by rapidly paced, high-tempo practices, and that lone day off for the players."

Also from Farnsworth: Matt Hasselbeck and T.J. Houshmandzadeh are getting in sync.

More from Farnsworth: Red Bryant stood out at the Seahawks' morning practice Thursday.

Bryan Burwell of the St. Louis Post-Dispatch says the Rams can take their cue from the crosstown Cardinals. Burwell: "Watch very carefully as the Rams get closer to the end of the preseason, because there will probably be a lot of changing faces. This is the new reality at Rams Park, and it is another sign of a franchise moving in the right direction. There are only a handful of players on this Rams team who should rest easy. When you've won only five games in two seasons, nearly everyone is replaceable."

Jim Thomas of the St. Louis Post-Dispatch says Rams coach Steve Spagnuolo established a fast tempo during training camp, according to safety James Butler. Thomas: "If you include the Aug. 7 scrimmage at Lindenwood, nine of the first 11 full-squad days of camp featured live tackling."

Also from Thomas: Five things to watch when the Rams face the Falcons in their second exhibition game. Rookie Jason Smith could win the starting job at right tackle with a strong performance, Thomas suggests.

More from Thomas: The Rams put veteran running back Ahman Green on their "ready list" after working him out this week.
