Plenty of reason to be optimistic about the Patriots' running backs this year and having AJ Brown out wide should help reduce the box counts that both face. Both of them faced an above-average number of box defenders last year, so lowering that will increase their xYBC.

Is yards before contact an offensive line stat? Less than we treat it like one. I took a deep dive on a stat that we may have been reading wrong, using a couple of different modeling techniques to explain why. You can read it FREE on my Substack 🔗⤵️

Rushing scheme diversity doesn't always lead to rushing success, but the Cowboys did a really good job last year of mixing up the concepts they used while having a very solid running game:

Just got back from an incredible week in Colombia! Learned about the concept of permaculture, toured Medellín’s Comuna 13, ate some delicious meals, enjoyed some stunning views, and so much more! Would highly, highly recommend a trip down there to anyone.
Also: if you read any or all of my six chapters in this year's book and wonder, "wow where is he working this season, what lucky outlet could that be?" well, that answer is still unknown. If you would like to change that, please reach out.
It's here! Get your copy of the Almanac. I promise there is no better way to get ready for the upcoming season. The level of craft and care put into this each year is unmatched. Honored each time I get to be a part of it and excited for it to be out!
The Almanac is 100% worth it and easily provides some of the best analysis to get you ready for the season! I also love that you get a collection of analysts writing sections to get a unique perspective on stats and trends.
Hey, it's Almanac day! All our hard work goes into this and we're very proud of this year's edition. Lots of surprising projections in here, and tons of useful and interesting stats about last season. You can get the PDF version now and the Amazon print version will be available next week.
I've returned from my writing hiatus to bring you some research I did on determining an explosive play threshold. Using scoring-probability added, I found the yardage at which a gain starts acting differently in terms of its impact on scoring. Read it FREE on my Substack 🔗⤵️

Just spent all week debugging an issue that was caused by a commit I made in January
I think I was rooting for the Sabres, but the crowd-deafening effect of an away OT goal is somehow so beautiful
I wrote about this at some point, I forget where/when and it probably doesn't exist anymore, but the other layer to RB wide/in the slot is that so many of those snaps just happen in empty and the target share of a RB in empty is typically so low, there's actually no meaningful impact to passing game
I’m a little late to the party, but I wrote about a controversial topic from the draft community. No, not consensus big boards… Instead, I used an analytical framework to determine how many games it takes to evaluate a prospect! You can read it for free on my Substack! 🔗⤵️

Want to see how the players your team drafted compare to prospects from past seasons? I went through each position and calculated sim scores based on player athleticism, production, and usage! You can read all of them on my Substack with the methodology in the first post! 🔗⤵️
