Undervalued:
DK Metcalf - Might be an unorthodox take, but his current ADP is an overreaction to Geno Smith. Yes, Metcalf will be worse without a competent QB. But he's being drafted as a high end WR3 in a lot of leagues, and at that point in the draft he's a steal. Garbage time is a real thing, and Metcalf is going to be getting by far the most targets in Seattle.
Overvalued - Drafting any quarterback early in a 1 QB league with 12 or less teams. It's just not worth it. There's always top 10 QBs who end up available on waivers if you strike out with your late draft pick, and after the top 3-4 QBs on the board, the drop off from 4/5 to 12 is usually not that significant. After the 2nd round of the draft, there's a cliff on RB quality, and most of the WR value is in the first 5-6 rounds. If I need to also pick a player, I'll go with Breece Hall. I'm not convinced that the Jets RBs won't be in a timeshare for the first half of the season, and while I like Breece a lot, his ADP of late 3rd / early 4th is too early for me.
