Peter Overzet uses fantasy football ADP from Underdog Fantasy to unearth mispriced players across three other fantasy football platforms -- ESPN, Yahoo!, and Sleeper.

Even if you haven't drafted a single best ball team this summer, you can leverage the best ball market to dominate your home leagues.
There are two main reasons why comparing Underdog ADP to home league ADP can help direct you to the best values in managed drafts:
Luckily for you, I've compared Underdog ADP to three of the major managed league platforms–ESPN, Yahoo!, and Sleeper–to highlight the most extreme values, as well as some insights on how to attack your draft on those specific sites.
Looking to compare ADP sources yourself? Our ADP tool has you covered!
From a macro perspective, there are a few common themes across all of these sites compared to Underdog:
Late Rounds:
Early Rounds:
Non-WRs:
There are a ton of great values on ESPN. The biggest thing that stands out is how cheap it is to attack the Jaguars passing game. With your Round 9, Round 10, and Round 12 picks, you can lock up the QB (Lawrence) and top two pass catchers (Kirk and Thomas).
I have a hard time imagining how Lawrence and at least one of those two WRs don't return massive value.
Some other undervalued pass-catching duos to target include the Packers (Doubs and Wicks), the Chiefs (Brown and Worthy), and the Bills (Samuel and Shakir). Taking two cheap stabs on these offenses gives you an affordable way to land a league winner.
The young WRs going in Rounds 6 and 7–Nabers, Dell, and Pickens–all look like smashes.
As far as the non-WRs, there are some nice prices on the TEs, although nothing compared to the WRs.
Because of this dearth of WR value in Rounds 6-10, I really like the idea of getting two elite RBs, an elite QB, and an elite TE early before hammering pass catchers after that.
Late-Rounds
Early Rounds:
Non-WRs:
We covered most of the extreme values in our perfect Yahoo! draft last week, but it is worth re-emphasizing how absurd the pricing is on some of these WRs.
Nabers and Worthy need to be part of your redraft plans on Yahoo. While you are at it, grab one of Dell or Flowers in the 6th.
There are some nice discounts on the Elite TEs, as well.
All of this points us to grabbing a couple of RBs in Rounds 1 and 2, and then hammering pass catcher for a long time. Just don't forget to make a pit stop for Brooks in Round 9.

Non-WRs:
Unfortunately, the extreme values are harder to come by on Sleeper where the ADP appears to be more efficient.
The Packers WRs–Wicks and Watson–look like solid targets here.
You could also set up a Seattle bet with nice prices on Metcalf and Fant.
