Expanding on an earlier post, this one ranks NFL players by most sacks per pass play through Week 13.

The San Francisco 49ers' Aldon Smith ranks fourth on the list. The St. Louis Rams' Chris Long is 10th. The Arizona Cardinals' Sam Acho ranks 19th. Ex-Seattle Seahawk Lawrence Jackson is 14th. Ex-Ram Adam Carriker ranks 21st.

Smith is keeping impressive company. The next step for him, likely next season, will be to maintain his pass-rush production as an every-down player, when he'll also have to hold up against the run more frequently. So far, so good.

The St. Louis Rams' Robert Quinn did not quite make the chart. He has five sacks and a 2.2 percentage. Seattle's Chris Clemons has eight sacks and a 2.1 percentage.

Sacks are not the only measure of a player's performance, of course. The best pass-rushers tend to collect a lot of them, however.

NFC West leads way in rookie sacks

A quick look through the NFL rookie sack leaders shows NFC West teams with three of the top 10 producers, led by the San Francisco 49ers’ Aldon Smith with 9.5.

This is how it should be.

NFC West teams drafted two of the first three outside pass-rushers in 2011.

Denver’s Von Miller, the first pass-rusher chosen, leads all rookies with 10. 5 sacks. The 49ers’ Smith, drafted seventh overall, was the second outside rusher chosen. The St. Louis Rams’ Robert Quinn, tied for eighth on the list with five sacks, was the third outside rusher chosen. Houston’s J.J. Watt has more sacks than Quinn, but as a 3-4 defensive end, he’s not a pure outside rusher.

Arizona’s Sam Acho has outproduced his draft status as a fourth-round choice. Acho has five sacks in the Cardinals’ past seven games, though three of Arizona’s past four opponents have held him without one.

Sacks aren’t the only measure of a pass-rusher’s performance. The good ones tend to rack up a lot of them, however.

Charles Haley holds the 49ers' rookie record since the NFL began tracking sacks in 1982. He had 12.5 sacks during the 1986 season. Dana Stubblefield had 10.5 sacks during 1993, his rookie season.

Smith needs 3.5 sacks over the 49ers' final four games to pass Haley. He has all 9.5 of his sacks in the 49ers' past nine games, including two during the 49ers' division-clinching victory over St. Louis on Sunday.
The Seattle Seahawks were on the clock with the 99th overall choice in the 2011 NFL draft when the Minnesota Vikings called to inquire about a trade.

Coach Pete Carroll and general manager John Schneider had a decision to make. The team wanted to add more picks, so sliding back into the Vikings' spot at No. 106 carried some appeal. But the Seahawks had not addressed defense to that point in the draft, and Mississippi State outside linebacker K.J. Wright was a player they had been targeting.

Seattle decided to stand pat at No. 99.

"It is rare that you would find a linebacker with that much length (6-foot-4) and 4.6 speed," Carroll said after the draft. "We need that flexibility."

This seemed a bit improbable. After all, teams selected 24 more linebackers over the remaining 155 selections. Surely one of them could have provided what the Seahawks wanted from Wright, right? Not necessarily. The more I studied those selections, the more I understood what Carroll was talking about. Wright was the fourth and final 4-3 strongside linebacker selected in the draft. All were gone among the top 100 selections.

The NFL has become so specialized, particularly on defense, that players are increasingly difficult to categorize. Seeking fresh perspective on the 2011 draft, I reclassified the 254 players chosen into 20 positional categories, based largely on how teams plan to use them. The process was imperfect because teams view players differently, and some players transcend easy categorization. But patterns that emerged were helpful in bringing the big picture into clearer focus.

Breaking down linebackers into five categories across 3-4 and 4-3 schemes was particularly helpful.

Teams selected one 4-3 strongside linebacker in each of the first four rounds, but none thereafter. They selected 12 4-3 weakside linebackers -- none in the first two rounds, five in the sixth and three in the seventh. That position carried less value relative to others based on when the players came off the board.

Nine of 11 4-3 defensive tackles went in the first three rounds, affirming how much teams value that position. Teams selected five 4-3 defensive ends in the first two rounds, then none until taking one in the fifth and four more in the seventh. Teams selected four five-technique defensive ends in the first round and one in the second, but none over the next four rounds.

I ultimately divided players into percentiles based on where they were selected in relation to other players from the same positional categories. Three NFC West players were the first players chosen at their specific positions. They were in the top percentile for their positions. Three, including Wright, were the last players chosen at their specific positions. They were in the bottom percentile.

The percentiles say nothing about whether individual players will succeed in the NFL. In some cases, players with lower percentiles probably carried more value at that moment in the draft based on how few prospects remained available at their positions.

Without categorizing players more specifically, we might not have any idea.

Overall, this draft featured 37 cornerbacks; 28 wide receivers; 24 running backs; 21 interior offensive linemen; 20 offensive tackles; 16 safeties; 13 tight ends; 12 quarterbacks; 12 4-3 weakside linebackers; 11 4-3 defensive tackles; 10 4-3 defensive ends; 10 3-4 outside linebackers; eight five-technique defensive ends; seven 3-4 inside linebackers; seven fullbacks; six 4-3 middle linebackers; four 4-3 strongside linebackers; four nose tackles; and two specialists. Two defensive linemen -- Kansas City's Allen Bailey and Baltimore's Pernell McPhee -- qualified as nickel pass-rushers.
