5 Training Camp Breakout Candidates You're Sleeping On in 2026

Every August, fantasy managers spend their draft capital on the same 40 names while five or six players are quietly dismantling defensive backs at training camp, earning rave reviews from beat reporters, and waiting to explode onto the scene the moment Week 1 kicks off. This is not a list of safe picks — this is a list of players who could make your league mates look foolish come November. Let's get into it.

1. Darren Waller, TE, Carolina Panthers

Stop writing off Darren Waller. We know, we know — the injuries, the age, the fact that tight end already feels like a position you're just hoping to survive. But Waller landing in Carolina is a more interesting situation than it's being given credit for. The Panthers have been aggressively building around a young offensive core, and a veteran safety valve at tight end is exactly the kind of security blanket a developing quarterback leans on when plays break down. Waller's receiving ceiling — when he is healthy and on the field — is unambiguous, and his track record as a pass-catching tight end speaks for itself. At rank #409, he's available late enough that the injury risk is already fully baked into the price. We're not saying he's a TE1. We're saying he could be, and you can get him for essentially nothing.

2. Caleb Douglas, WR, Miami Dolphins

The Dolphins have quietly assembled one of the more intriguing wide receiver rooms in the AFC, and Douglas is the one making noise that nobody outside of Miami beat writers seems to care about. Sitting at rank #240 in current Sleeper ADP, Douglas is practically a free player in most drafts — which is exactly the kind of low-cost, high-ceiling flier that wins fantasy championships. Miami's offense, when healthy and clicking, has been a top-five fantasy unit in terms of volume and pace. If Douglas carves out a defined role in the slot, we're talking about a genuine WR3/flex option available in the double-digit rounds. Draft him, stash him, thank us in Week 6.

3. MarShawn Lloyd, RB, Green Bay Packers

Here's the hot take you didn't ask for: MarShawn Lloyd could be the most valuable late-round running back in your 2026 draft. Green Bay's backfield has been a graveyard for fantasy optimism for three straight seasons, but Lloyd's skill set — quickness between the tackles, legitimate receiving chops out of the backfield — fits a Packers scheme that desperately wants to manufacture touches in space. He's currently ranked #208 on Sleeper, which means most of your league is either ignoring him entirely or has him penciled in as a handcuff afterthought. Lloyd is not a handcuff. He's a weapon waiting for a role to crystallize, and training camp reports suggest the Packers' coaching staff sees exactly what we see. Take him three rounds before you think you need to.

4. Barion Brown, WR, New Orleans Saints

We'll be honest — New Orleans is not a destination that screams fantasy relevance heading into 2026. But that's precisely why Brown at rank #549 is the kind of contrarian play that separates real analysts from the casuals. Brown has the route-running refinement and contested-catch ability to force his way into a Saints passing game that, quite frankly, needs a credible deep threat. If New Orleans finds any semblance of offensive consistency this season, the targets have to go somewhere. A receiver with Brown's tools sitting essentially undrafted in most leagues is a dart throw worth taking in the final two rounds of any format. The risk is near zero. The reward could be a top-30 fantasy WR finish.

5. Cyrus Allen, WR, Kansas City Chiefs

Here is the most dangerous kind of fantasy football player: someone playing for the Kansas City Chiefs with a defined role and Patrick Mahomes throwing him the football. Allen currently sits at rank #203, which feels like market correction waiting to happen the moment he posts a 6-catch, 80-yard line in a preseason showcase. Kansas City has a well-documented pattern of manufacturing fantasy-relevant receivers out of thin air — the names change every year, the production finds a way. Allen's size-speed profile suggests he can win outside, and in an offense that consistently generates elite touchdown volume, there are points available for a new face to claim. We'd strongly consider Allen as a WR3 target in the 9th or 10th round before his rank craters ahead of Week 1.

Training camp is the single best time to gain a fantasy edge, and that edge evaporates the second the mainstream press catches up to what we're watching. These five players represent the clearest cases of market inefficiency we've identified heading into draft season — but the window is closing fast. Bookmark this page, come back after the final preseason week, and we'll tell you exactly which of these names to trust with your last flex spot and which ones the depth chart quietly passed by. The 2026 fantasy season is won right now, in August, while your competition is still arguing about first-round picks.
