2021 RSO IDP Defensive Line Review
Welcome back you IDP connaisseurs! Let’s continue our journey into the IDP world of fantasy football. We will kick off our review of the 2021 season, with the DL position group. If you recall from our intro to IDP, the DL position(s) is one that can be dictated by two key factors, the first, and most important for all IDP success, is the volume (as it is for most fantasy positions). The second factor is the NFL player’s ability to win their one-on-one matchup at the line of scrimmage. The defensive line is the unique position of IDP that generally correlates IDP success based on NFL success, similar to the offensive side of the ball. These will be things we want to keep in mind as we go forward through IDP.
Before we look at those top-performing pass-rushers from 2021, we must look at who is designated as a DE or DT. Figuring that out though is tough because defense in today’s era of the NFL is not the same kind of football from 1990 through 2010 or even just 5 years ago. Part of that understanding is that so many times people throw around the term “3-4 base” or “4-3 base” as a point of how to identify or designate players. However, thanks to the talented Tom Kislingbury (@tomkislingbury on Twitter), this base defense generally doesn’t account for more than roughly 8,000 snaps across ALL TEAMS AND 17 GAMES! Down from nearly 12,500 in just 2014! The point of this tangent is to call out that NFL defenses run so many different packages and looks, just like NFL offenses do and that has left us in a precarious situation in which we are not always accurately identifying or designating defensive players. And the greatest offender to this is in the DL position group.
Let’s get back on course and take a look at our top 24 (ish) “defensive linemen”, and you will see the top 12 on RSO based on designation and then the other “DL” or “EDGE” players that get LB designation (scoring is based on IDP123 scoring):
Cool, a table that shows the top 12 DL in RSO and those you can’t use due to designation, you say. But the table highlights our initial article about understanding your league’s roster composition and the difference between elite DLs and those at the replacement level. If you got inside the top 5 for this position, you were very happy with the production of your DL spot(s). It also showcases the need to understand positional designation for your leagues as well. Then, how do we get it so you can identify these players for you so you can get them on your roster?
For IDP, the first piece is getting on the field, and understanding an IDP’s snap counts is the first step to finding those who will succeed. The next step at the DL level is those who are winning their reps as much as possible each play. When you find that intersection you will see the top of your list here.
After this elite level, you see things start to mix up with either higher snap counts (800+ total or ~50 per game) or consistent QB Pressures ( 50+ total or ~ 3 per game). These are baselines and basic analytics you want to search for to help you with your search for consistent IDP DL production. As for the Pass Rush Win Rate, this is a PFF analytical stat, so you can rely on a source like them to provide this via their site or you can use the eye-test if you are able to watch enough games or replays to see which defensive linemen are winning those snaps each play at a consistent rate and getting to the QB. I like the mix of this to help round out my search for my IDP assets.
Well, picking out All-Pro and Pro Bowl players is easy because that is what this list looks like. While you are correct, there are outliers and information in both directions that can help us avoid making mistakes or help us find the next top performer. Looking at players who had an abnormal amount of snaps (Cameron Heyward is up almost 125+ snaps based on previous 4 seasons’ averages) or one who showed consistent success with QB pressures but just did not find a way to convert this into statistical success. Examples from this past year would be Maxx Crosby (100 pressures, first in the league) and Rashan Gary (81 pressures, third in the league).
The last point I want to call out is to pay attention to players’ and coaches’ movements when it comes to IDP position designation. This is still an inexact science at this point and as you can see from the first table, there are players who are true pass rushers but have that LB designation so they don’t get to score at a DL position. And as defensive coaches and schemes change, LB and DE position changes can change along with it like Chandler Jones moving from Arizona’s “3-4 base” to Las Vegas’s “4-3 base”, will he stay with the LB tag? Will he shift to DE? And the inverse for Danielle Hunter (assuming he stays with Minnesota), where will his designation end up?
I hope this gives you some insight as to who the 2021 successes were, how they got there, and how you can work to understand it going forward for your drafts, trades, or anything else IDP related!
