Reddit mentions of The Los Angeles Rams 2017 3rd Down Manual

Double comment, but Robert Peters is a good person to look at for football strategy stuff.

This is a breakdown of the ram's third down offense from last year, and he's got a bunch of other stuff getting into the bones of how offenses run.

Yeah there a couple simple factors behind what the Rams do with their personnel

1. A massive part of playcalling is knowing what the other teams defensive rules are for coverage. You simplify the number of responses and checks a defense can have when you stick with one personnel grouping they become a lot more predictable. The focus in many ways of them doing this isn't "We are trying to confuse you and dictate the terms of engagement" it's "We just want to understand what you do and respond to do you, we will react to you". Great article here showing how McVay calls based off understanding a defenses rules
   
   
   
2. This is article gets at a very key point: everything the Rams do looks the exacts same before the snap note the point below in particular
   
   
   While most NFL coaches talk about how they want to keep defenses guessing by making every play look the same, McVay actually does so by giving defenses run action on more than 95 percent of under center looks, no matter if it's a tailback handoff, an end around to a motion man or a play action pass."
   
   
3. I strongly recommend this book for anybody who actually wants to know how the Rams playcall. What you will notice is about half of their 3rd down passing plays if you read the book can be distilled down to about a half dozen concepts. Again number of plays doesn't matter it's having the right play against the particular coverage.
