2023 Fantasy Football Defense Stream-O-Matic

Welcome to the 2023 Fantasy Football Week 10 Defense Stream-O-Matic!

With the Kansas City Chiefs, Philadelphia Eagles and Miami Dolphins on bye weeks, the Cleveland Browns defense going up against the Baltimore Ravens offense and the Jacksonville Jaguars matching up with the San Francisco 49ers, there will be a handful of managers in every league looking for a streaming option in Week 10.

I hope this tool will be helpful when deciding between tough options this season. Last year, I was tracking the results of the Defense Stream-O-Matic, uploading its rankings to FantasyPros. It turned out to be the most accurate ranking of defenses through Week 17! The more in-season data we get, the more accurate the tool becomes!

I use a traditional rotisserie scoring style commonly used in fantasy baseball season-long leagues to give point totals to each team.


The categories for the chart are listed below along with links to websites that I use to find this data.

  • Rost%/Start%: Roster percentages based on Yahoo Fantasy Football leagues. This gives us an idea of who is available. This doesn’t factor into the standings and data will be updated after Waivers.
  • Location (Home): Generally speaking, defenses play better at home than on the road. A five-point bonus is given to all home teams.
  • Vegas (Opp Implied): Using Vegas odds, the spread and over/under generate an implied points total for each team. This game score portrays what the game flow could look like and, therefore, which Fantasy Football defenses are in a good position to succeed. This data will be updated later in the week to adjust for breaking news, injuries, etc.
  • Pressure (Opp Prss%): Thanks to Pro Football Reference, we have access to advanced passing statistics. I focused on pressure percentages allowed here which includes QB hurries, hits and sacks.
  • DVOA: Probably the most popular tool for evaluating defenses, the DVOA efficiency ratings are utilized to give a strong baseline to the rankings. FTN Fantasy has weighted DVOA that I am using for Week 10.
  • ECR: The team that is ranked No.1 on FantasyPros ECR for the week gets the maximum points for the week. This data will be updated later in the week to adjust for updated rankings.
  • Fantasy Points Allowed -I am now mixing in Fantasy Points Allowed as a scoring category. This gives the team facing the Giants a bump vs the defense facing the Ravens.
  • Proj: I used Yahoo Week 10 projections for this column. It is added as a bonus and not scored like roto for all the other columns. This data will be updated later in the week to adjust for updated projections.

Appreciate the easy to process data! What do you make of the 49ers with the recent acquisitions? Are they still an “elite” tier defense?

San Fran hasn’t really been a good fantasy defense this season with just two double-digit performances – they are barely a top 20 defense according to fantasy points scored

Chase Young will help but their strength of schedule remaining is just average

Even DVOA says the 49ers defense has been just average
