Over the past couple of years, you’ve probably heard NFL and fantasy analysts discussing a shift in the offensive meta, specifically the rise of 12 and 13-personnel packages. But what does it actually mean, and does it have any real impact on your dynasty teams?
The short answer is yes. In today’s article, I’ll break down the “why” behind it, but first, let’s make sure we’re all speaking the same language.
If you’re unfamiliar, here’s what it means when someone refers to “X-personnel”:
11 personnel — 1 RB, 1 TE, 3 WR
12 personnel — 1 RB, 2 TE, 2 WR
13 personnel — 1 RB, 3 TE, 1 WR
21 personnel — 2 RB, 1 TE, 2 WR
22 personnel — 2 RB, 2 TE, 1 WR
These five groupings make up the majority of NFL play-calling year over year, and the balance between them is shifting in ways that matter for how you build your roster and prioritize certain fantasy players.
For this article, I pulled NFL leaguewide data dating back to 2022 from sumersports.com, and have confirmed that TE-heavy packages are steadily increasing, while 11 personnel is decreasing across the league.
