The Biggest ADP Mistakes Fantasy Managers Are Making Right Now
The most chaotic part of the NBA offseason can open the door to new possibilities for next season's fantasy draft board.
It can also lead to fantasy managers making a ton of mistakes when it comes to fluctuating ADP.
There have already been some massive deals this offseason (Giannis, Kawhi, LaMelo, you know the names), and there will be more before training camps get underway. There's one core problem: ADP data structurally lags fast-moving news, and that lag is where mistakes happen.
Lucky for managers, these gaffes are avoidable. Here are the five biggest fantasy basketball ADP mistakes.
Mistake 1: Trusting a Stale Draft Board
The days-long lag for ADP aggregators and mock drafts can make a draft board from early June very behind the times by early July. Think of how different ADPs are for players on the 76ers and Celtics following the Jaylen Brown-Paul George trade, especially VJ Edgecombe. (You can read more about that here.)
Fantasy managers can avoid this mishap by spot-checking personal rankings against roster moves throughout the offseason and up to 48 hours before their actual fantasy drafts. A quick check can help owners make small tweaks throughout the summer to keep their draft boards fresh.
Mistake 2: Assuming Every Player Near a Trade Is Affected Equally
Trade headlines create a blanket effect across an entire roster. In reality, the roster on the receiving end of a trade can be impacted in different ways. The Kawhi Leonard trade to the Raptors will negatively impact RJ Barrett and Immanuel Quickley, while Scottie Barnes' large role is expected to stay intact.
The same goes for the Ja Morant trade to the Trail Blazers. Morant's presence squeezes Scoot Henderson and Jrue Holiday in the backcourt, while Deni Avdija's minutes and usage in the frontcourt should stay the same.
The quick fix to this mistake: Don't blindly trust the headline reaction. Owners should note last season's usage, then keep an eye on depth-chart movement leading up to training camp.
Mistake 3: Confusing Dynasty ADP With Redraft ADP
This mistake happens more often than you might think.
Redraft ADP addresses single-season worth. Dynasty ADP addresses multi-year worth. And the prices for the same player can be widely different between the two lists.
Blending the two leads managers to one of two mistakes: Overpaying for long-term upside in a one-year league, or underpaying for immediate role clarity in a keeper league. Think overpaying for Caleb Wilson ahead of his rookie season when he's more valuable on a dynasty roster. Or underpaying for Steph Curry in a keeper league when he can add immediate value in the 2026-27 season.
Managers simply need to double-check which ADP list they are using to make sure it matches their league format.
Mistake 4: Paying For Name Recognition Instead of Current Role
Perhaps the most common mistake of them all, because it's easy to be blinded by celebrity status. A star player's name and reputation can overshadow his actual touches, especially right after a trade when the market hasn't fully processed his new role.
Plenty of fantasy managers will make this mistake when LeBron Jamesjoins a new team this offseason. His star power carries a lot of weight, but can overshadow what his current role will be on a new team. This will lead to owners overpaying for James but getting less mileage out of him. (And that's before you factor in age regression and all his load management days.)
Don't get blinded by a marquee name. Always look at depth charts and check for role clarity leading up to fantasy draft night.
Mistake 5: Building a Board Too Early and Never Rechecking It
We aren't saying managers shouldn't start building their boards early. Far from it, actually.
What owners don't want to do, though, is build it early in the summer and then not adjusted before the draft. Preseason news, training camp battles, and late free-agency moves keep ADP fluid, even after the initial late-June trade wave settles. That makes boards frozen in early July outdated by draft day in September or October.
ADP isn't a fixed number. It's a lagging indicator that requires constant verification, especially during an active offseason with a ton of roster movement. So, managers should consider rechecking their draft boards at least weekly, even if there isn't a big trade in the works.

Questions About ADP Mistakes, Answered
What is the biggest fantasy basketball ADP mistake managers make?
Trusting a stale draft board is the biggest mistake. ADP data often lags behind major offseason news, so draft boards built weeks earlier may no longer reflect current player value. Spot-checking rankings against recent roster moves and updating them close to draft day helps keep projections accurate.
Does a trade affect every player on a roster equally in fantasy basketball?
No. Trades impact players differently depending on their expected roles, usage, and depth-chart position. While some teammates lose touches or minutes after a major addition, others may see little change. Reviewing projected roles instead of reacting to headlines leads to better draft decisions.
Should I use the same ADP for dynasty and redraft fantasy basketball leagues?
No. Dynasty ADP reflects long-term value, while redraft ADP focuses only on the upcoming season. Using the wrong list can result in overvaluing long-term prospects in one-year leagues or undervaluing veterans who offer immediate production.
How often should I update my fantasy basketball draft board during the offseason?
Managers should continue updating their boards throughout the offseason and make another review close to draft day. Weekly checks can help account for trades, training camp developments, and late free-agency moves that continue to shift ADP before the season begins.
