Unblocked Pressure: 2014’s Top Players

unblocked-pressure-wattLast season we took you on a tour through some of the numbers from deeper in our database as we gave you a look at the most productive teams and players at generating unblocked pressure. A year on we’re splitting that data in two and in this article we’ll be looking at the top players and taking a quick look at the most productive unblocked pass rushers from last season to see whether their production carried over from a season ago.

A Familiar Face on Top

You would think that as the league’s most destructive pass rusher J.J. Watt simply wouldn’t have the unblocked opportunities to rack up sufficient numbers to lead the league, but that’s exactly what he did. His 16 unblocked pressures are fewer than both Lavonte David (19) and Brian Robison (17) collected to be first and second a year ago, but were enough to ease him clear of Clay Matthews for the league’s best mark in 2014.

Increased opportunities on the edge of the defense this season saw Watt gain opportunities to harass opposing quarterbacks unattended and he took full advantage converting a quarter of his unblocked pressures into sacks and 13 of 16 into a hit or sack. If it wasn’t already clear enough that you shouldn’t leave Watt unblocked in any circumstance, that knockdown percentage should leave you in no doubt.

Another player to feature prominently was Connor Barwin who feasted both as an unblocked defender and cleaning up when other defenders had created pressure and flushed the quarterback from the pocket. Barwin’s 56 total pressures were fourth-most among 3-4 outside linebackers last season but a large percentage of those came unblocked, in clean up, or pursuit. 26 of his 56 pressures came in one of these cases with nine of 16 sacks falling into these categories. On average, edge rushers got around 30% of their pressures in one of these three categories while Barwin collected 46% of his pressure this way.

Making the Most of their Opportunities

Taking advantage of unblocked opportunities to pressure the quarterback is one thing, finishing the play and knocking the quarterback down with a hit or a sack (as Watt so often did) is taking far fuller advantage of the opportunity provided. For example, both Pernell McPhee and Calvin Pace were in a group tied for 10th place with 11 unblocked pressures last season, but while McPhee converted six of 11 into sacks (two) or hits (four), Pace converted only one of his 11 unblocked pressures into a hit or sack.

The best knockdown percentage for any defender who recorded at least six unblocked pressures last season was Keenan Robinson of Washington who knocked the quarterback down on all six (1 Sk, 5 Ht) of his unblocked pressures. Looming large near the top once again is Watt with C.J. Mosley’s knockdown percentage of 69.2% very impressive from his 13 unblocked pressures.

Meanwhile, at the other end of the scale, the likes of Brandon Graham, Cameron Wake and Justin Houston couldn’t match that conversion rate, registering no more than one unblocked hit or sack with at least six unblocked pressures to their names.

Maintaining Unblocked Production

A valid question to ask is whether unblocked production is consistent? Is there too large an element of luck involved in it or is it a measure of scheme and hustle leading the same names to crop up towards the top of the list in successive seasons.

As it happens, a couple of familiar names did rise in each season, though there was plenty of turnover at the linebacker position. This was led by Lavonte David whose unblocked production fell away with the rest of Bucs’ defense, thanks in large part to a change in defensive scheme. A number of the top edge defenders from a year ago stayed toward the top of the list, though, and in Brian Robison’s case maintained a similar profile in terms of conversion. Second to David a year ago with 17 unblocked pressures, Robison racked up 12 in 2014 to remain inside the league’s Top 10 but in both seasons converted only two of his unblocked pressures into a sack or a hit.

One spot where we saw a change of name but same role retaining the unblocked production was Todd Bowles’ inside linebacker in Arizona. Karlos Dansby was sixth in the league with 13 unblocked pressures a year ago for Bowles and after his departure his replacement, Larry Foote, took Dansby’s spot inside the Top 10, finishing tied for seventh with 12 pressures. Jets fans will doubtless be expecting to see David Harris or Demario Davis included when we come to reveal the 2015 numbers in 12 months time.

    It’d be interesting to see this limited to DL (including 3-4 OLB, & 4-3 OLB who are primarily rushers on pass-plays), since many of the people appearing on the various lists are DBs or (non 3-4 outside) LBs, players who are usually blitzers or schemed to be unblocked (and perhaps wouldn’t even be blocked by an offensive lineman).

    • Chris

      Due to the high ratio of unblocked rushes for 3-4 OLBs (30%) I’d rather just see the DL.

      • LightsOut85

        In that paragraph they just said “edge rushers” so I think that includes 4-3 DE too (and, I didn’t notice that line initially, so thanks for making me go back & see it :) ).

    Would love to have % of pressure that came unblocked listed on all defenders grades as a sortable stat, especially for rushers. Should be a key part of their grade anyway as they didn’t really have to beat anyone to get the pressure, so why not let us see which pressure #s are truly based on their skill to beat someone instead of benefitting from blind oline or a good blitz scheme.

      but as the stats clearly show being unblocked doesn’t automatically result in production, so while the physical skill needed isn’t as high on these particular plays the play diagnosis required and extra hustle is necessary still

      • Chris

        Compare the following players unblocked knockdown percentage with their overall knockdown percentage, using the charts above:

        Watt: 81% unblocked, 55% overall
        Matthews: 53% unblocked, 44% overall
        Barwin: 50% unblocked, 48% overall
        Kerrigan: 43% unblocked, 31% overall
        Walden: 78% unblocked, 66% overall

        All 5 guys saw increased production when unblocked, and 4 of them saw vast increases (Barwin being the exception).

        So yes, being unblocked doesn’t automatically result in production. But it certainly makes things easier. So logically, guys who have more free rush chances are going to have inflated stats. The more free rushes the more inflation.

        Just like how they have a QB Accuracy % that excludes dropped balls and throwaways, and a WR Drop Ratio that excludes uncatchable balls, I’d like it if they could post a Pass Rushing Ratio that excludes free rushers. Because some guys benefit from unblocked rushes more than others. If I remember correctly Aldon Smith was one who really benefited from unblocked rushers when they ran the article last year.

      I’d love to see a LOT of things that have been “article exclusive” added to the premium section. Namely, pass-rushing by down (compare “obvious passing down” PRPs**), and routes by WRs (specifically YAC/MT, but everything broken down by route would help compare WRs more directly, rather than “based on what they’re asked to do”).

      **The last time they did this, Justin Tuck scored very well – even though his overall PRP was pretty bad. On the Giants he was probably asked to play the run first & so looking at just 3rd/4th let you compare him more equally to guys who pin their ears back every down, run plays be damned.
