FootballOutsiders: What to expect in the future of OL evaluation Once again Tyler Lockett Jersey , FootballOutsiders has lended itself to SB Nation, answering five questions from each blog about their team. These questions and answers should slant towards the advanced analytics that FO focuses on, specifically in regards to DVOA. To find out more about the great work at FootballOutsiders, you should definitely be keen on their annual almanac, which is available now in the FO Store.On Monday, we talked about Thomas Rawls, Eddie Lacy, and the 2017 RB problemOn Tuesday, it was all about Brian SchottenheimerToday, we’re looking at how advanced analytics could better serve the evaluation of offensive linemen.Q: From our writer John Fraley: “Do you have designs on exploring advanced OL stats beyond adjusted line yards? Or is that a fool’s errand?”Bryan Knowles:I wouldn’t call it a fool’s errand, but it’s very difficult. We have a number of stats measuring offensive line play – adjusted line yards, adjusted sack rate, pressure rate, stuffed percentage Authentic Frank Clark Jersey , power success and so on – but it’s all sort of only covering the offensive line in a reflective sense. Skill position players are easy – so and so passes the ball, so and so catches it, so and so runs off-tackle – but how much credit do you give the line for each play, and how do you separate that from overall team success? That’s a real challenge, even before you start to think about crediting individual linemen.We’ll likely never have DVOA or DYAR for linemen, because any useful rating system for linemen has to include subjective factors. We keep track of these things – our partners at Sports Info Solutions chart blown blocks on both the individual and team levels, and try to credit sacks to individual linemen – but without knowing the actual blocking assignments on each play, many of these decisions are going to be judgment calls. Which lineman was responsible for the lineman who split the A-gap; did the left tackle blow his block or did the quarterback hold the ball for too long, and so on and so forth. The nice thing about DYAR and DVOA is that it’s objective – play X gained Y% more yards than average against a defense that is Z% better than average. While we tinker and work with the system in the offseason to make it more predictive, we’re not assigning subjective qualities to each play and presenting it as a final rating. We prefer to let the rating speak for itself, and then write about more subjective and charting elements that help interpret the numbers (see our annual adjusted interception article, for one). That’s not really possible to do for offensive linemen with the data we currently have, and so we’re it’s unlikely that we’ll roll out a new rating system in the near future.That being said, the data is always improving. We have a new partnership with EdjSports which gives us some more tools to use Youth Will Dissly Jersey , and the NFL’s Next Gen Stats are providing more and more interesting stuff each year. I doubt we’ll have an offensive lineman-specific stat in the near future, but we may be able to provide more splits – which teams run best with a pulling guard, or which linemen get extra blocking help from tight ends on a regular basis. We’re always looking to provide new things!Mirage or Oasis? Projecting the rest of the Seattle Seahawks’ 2018 season Sunday afternoon saw the Seattle Seahawks crawling out of the NFC West basement by (finally) winning a game, toppling the Dallas Cowboys 24-13 at CenturyLink Field. On the face of it, an 11-point win at home, with a 100-yard rusher and a +3 turnover differential might make you think that the team has officially turned the corner. I’m here to pour a tiny bit of cold water on that notion.Even Pete Carroll couldn’t help himself post-game when he talked about playing the game they wanted to, particularly with running the ball and controlling field position via the punting game. The thing is, though...The running game was bad, it was inefficient, wasteful at times and ill-advised.Using data from Warren Sharp’s Sharp Box Score, we see that the Seahawks ran a whopping17 times on 1st down alone for a grand total of 39 yards, which comes out to 2.3YPC and 41% Success Rate. Both of those metrics, YPC and Success Rate were below league averages of 4.2 YPC and 44% respectively in 2017. While running on 1st down is generally inefficient, the Seahawks were more inefficient than usual and yet committed to doing so on a horrifying 68% of their first downs. It’s one thing to commit to a philosophy http://www.seahawksauthorizedshops.com/authentic-michael-dickson-je... , it’s another to stick to a philosophy that regularly puts you behind the sticks when you know you’re either bad at it or doing it far too often.The Seahawks are again being far too conservative on 4th down. Right after intercepting Dak Prescott (and having a huge return wiped off the board), the Seahawks had a three-play drive for six yards ending with a drop by Brandon Marshall. The ball was on the Dallas 45-yard line, the Dallas defense hadn’t exactly looked great to that point, and the Seahawks defense has looked shaky for the previous two weeks. Rather than go for it on 4th down, the Seahawks punted 38 yards (dragging Michael Dickson’s average punt yardage down). Assuming even a league-average chance of making the 1st down, the Seahawks stood to benefit more by going for it than had they punted. Work done ages ago by Brian Burke and Kevin Quealy shows how NFL coaches continued to leave points on the field by being too conservative on 4th down.The pass rush finally showed upThe defense got pressure on Sunday in ways they didn’t over the previous two weeks, with 10 QB hits of Dak Prescott, 5 of which were sacks, and a pair of interceptions courtesy of Earl Thomas (Tongue in cheek: “Pay the man!”). The reason for cautious optimism here is three-fold. First, the Dallas receivers are legitimately bad, generating little separation at the line of scrimmage or late in routes. Secondly, the offense has been described as remedial in some circles, even garnering stinging criticism from former Cowboy WR Dez Bryant and is the butt of a great many jokes on Twitter. Most importantly however is the situation on their offensive line. Pro Bowl center Travis Frederick is out indefinitely with Guillain-Barr茅 syndrome, rookie second-rounder Connor Williams has been struggling mightily at guard Bradley McDougald Jersey , and La’el Collins is doing his best Germain Ifedi impression at right tackle. With those things in mind it’s hard to get too excited by the performance. We’ll have to wait until the Los Angeles Rams home game in two weeks before we can draw any solid conclusions about their effectiveness, or lack thereof.After reading this, you might be thinking that I’m completely down on the Seahawks, and that couldn’t be further from the truth. I like Chris Carson as a player even if I think the Seahawks are using him poorly (give him the ball in the air).I happen to think that Russell Wilson, when he’s on his game, is a great player and he showed some of that on Sunday with a number of decisive throws into really tight coverage, including the TD to Tyler Lockett.Mostly though it comes down to schedule. The Arizona Cardinals are bad, the San Francisco 49ers just lost their franchise QB Jimmy Garoppolo for the season and the Oakland Raiders are a dumpster fire, courtesy of Jon Gruden. That makes for five very winnable games this season, even if everything else is a complete toss-up.There are definite bright spots looking forward but it’s still impossible to say if they’re a mirage or the real deal.
