Buying Breakouts Before They Break Out with JJ Zachariason
JJ Zachariason of Late Round QB has spent 14 years building analytical frameworks that help fantasy managers find value before the market catches on. In Episode 44, he walks Jeff through his ZAP Model, his new Market Score metric, and the signals he uses to identify breakout candidates. After naming a few of them, he warns that the window may have already closed.
“You can't buy right before the breakout. You gotta buy months before the breakout.”
Episode Summary
In Episode 44 of Dynasty Compass, Jeff Blaylock sits down with JJ Zachariason, founder of Late Round QB, to explore one of dynasty's most valuable and underused edges: identifying breakout players in their second and third NFL seasons before the market figures it out. JJ traces his analytical journey from a marketing degree and a self-published e-book to a 14-year career built on asking better questions than everyone else — and then building models to answer them.
JJ explains his ZAP Model, which projects a player's fantasy ceiling using the best two seasons across their first three NFL years, weighted against draft capital, college production, size, age, and program strength. He then introduces his newest tool, Market Score, which applies similar logic to redraft ADP — revealing which players are outperforming or underperforming what the prior-season data would actually predict. At certain positions, particularly tight end and middle-round quarterback, Market Score is dramatically more predictive than ADP alone.
The conversation covers the specific signals JJ looks for at each position: mobility at quarterback, pass-catching volume (measured by yards per route run) at running back, per-route efficiency at wide receiver, and athleticism plus college production backbone at tight end. He makes the case that talent is stickier than environment, that injuries matter mostly through the lens of cost, and that dynasty success depends on two equally important pillars — production and market value accumulation — with the hardest part being the willingness to finally go all in and convert value into wins.
JJ closes with specific 2026 breakout candidates at running back (Jonathan Brooks, Bhayshul Tuten, Keaton Mitchell, Jaylen Warren), wide receiver (Luther Burden, Zay Flowers, Jaylen Waddle), and tight end (Dalton Kincaid, Terrance Ferguson), plus honorable mentions for Alec Pierce and Josh Downs. He cautions that several of these players are already rising and that the most common mistake dynasty managers make is paying for a breakout before it actually happens.
Key Takeaways
Breakout, analytically defined: a player who outperforms his ADP expectation by a meaningful margin, not just someone who puts up big numbers.
The ZAP Model measures the best two seasons across a player's first three NFL years and uses draft capital, college production, size, and age to project that outcome.
Market Score uses redraft ADP instead of draft capital, adds prior-season efficiency metrics, and produces a score showing how many PPR points per game above or below ADP expectation a player should score.
Pass catching at running back remains undervalued by the market. Yards per route run in the prior season is one of the strongest signals for middle-round RB breakouts.
Tight end is the easiest dynasty position to find breakout value — managers give up too soon, and cost stays low longer than it should.
"Too late" arrives earlier than you think. By the time the breakout is confirmed by early-season stats, the price has already moved.
Dynasty has two pillars: production and market value. Accumulating value without committing to winning is JJ's self-described biggest flaw — and one he's actively working to correct.
