The Detroit Lions are betting against one of the NFL's biggest training camp trends, with not a lot of evidence that they'll win

Detroit Lions are ignoring a training camp trend that 28 NFL teams are embracing. The reasoning makes sense, but there is a notable downside.

The Detroit Lions are doing something different this training camp, and it speaks volumes about the franchise’s identity heading into 2026. Detroit is skipping joint practices entirely, joining only the Denver Broncos, Kansas City Chiefs, and Pittsburgh Steelers as the four NFL teams choosing not to hold a single joint session. The other 28 teams are all participating in at least one, with the New Orleans Saints and Tennessee Titans going all in with three separate sessions each. For a team whose head coach used to be one of the league’s biggest joint practice advocates, it’s a significant philosophical shift worth examining.

Dan Campbell completely changed his mind

If you followed the Lions over the last few years, you know Campbell was never anti-joint practice. He routinely talked about how valuable they were because players got to compete against someone wearing a different helmet. Different offensive linemen, different receivers, different pass rushers. Campbell often argued those joint practice snaps were more valuable than preseason reps because the environment could be controlled while still offering legitimate outside competition.

So what changed? Back in March at the Annual League Meeting, Campbell announced Detroit wouldn’t hold any joint practices in 2026. His reasoning was straightforward: he felt joint practices had become counterproductive. He doubled down on that stance during mandatory minicamp in June, making clear this wasn’t a scheduling conflict or logistical issue. It was a deliberate philosophical decision. Instead, the Lions will hold internal practices between late July and late August, sandwiched around 2 road preseason games and 1 at home, and they have no intention of dialing down their normal intensity in those practices.

What the Lions gain from staying home

The first benefit that comes to mind is health. The Lions have dealt with significant injury problems over the past few seasons, and training camp intensity has often taken the blame. You have to understand the logic here. If your core is already established, and Detroit’s absolutely is, why add unnecessary risk? Jared Goff isn’t competing for a job. Amon-Ra St. Brown, Penei Sewell, Jack Campbell, Brian Branch, Aidan Hutchinson. These guys have their roles locked down.

When you already know who your starters are, maybe you don’t need to put them into another physical situation just to confirm what you already know. Maybe you can create the competition you need internally. That’s a luxury. Not every team gets to operate that way, and you can understand why a team like Tennessee or New Orleans might schedule 3 joint practices when they have 48 guys on the roster who still need to prove they belong.

The trade-off nobody wants to talk about

Here’s the thing, though. There is a group that loses in this decision, and it’s the guys at the bottom of the roster. If you’re player No. 49, 50, 51, 52, or 53, if you’re an undrafted rookie trying to steal a roster spot, joint practices mean something. You get reps against starters from other teams. You get a chance to show something in a different environment. If you can win against somebody else’s starters, you have a real shot at earning a role.

Sure, those players will still get preseason reps. But the Lions aren’t putting their starters out there in preseason games, and frankly, most teams aren’t either. So some of those bottom-of-the-roster guys are losing evaluation opportunities they previously had.

This is about confidence, not fear

This decision isn’t driven by injury fear. There’s no public data proving joint practices are inherently more dangerous than internal sessions, or that skipping them leads to better health outcomes. A former player now working in physical therapy discussed how building a physical callus early in camp actually matters. Going out and hitting prepares the body for the regular season. He alluded to the idea that teams taking it too easy might be the ones dealing with early-season injuries because their players’ bodies aren’t conditioned for full-speed contact.

This is about confidence. The Lions believe they know who they are. They believe their starters don’t need outside validation. They believe they can get the work they need without bringing in another team.

But the trade-off is real. Losing those evaluation reps for the final roster spots could cost them. We’ll find out in late August whether Detroit feels like it had enough information. If the Lions miss on a few roster decisions, people will absolutely point back to this choice. If they don’t, it’ll just become another example of a contender operating differently because contenders can afford to.

That’s really what this story is about. Not whether joint practices are good or bad, but what it says about where the Detroit Lions believe they are as a football team heading into 2026.
