Deep dynasty leagues are becoming increasingly popular. Today, I’d like to talk about my experiences with the format, things to look for when joining a league, and what this means for the fantasy baseball industry.
Let’s start by defining a “deep” dynasty league. This is a flexible concept. In a recent poll, I said the following: “Let’s define “deep” as any mixed league that rosters 700 or more players leaguewide or any AL/NL Only with 350 or more players. At least half of players are kept.”
Again, the exact definition can vary. What matters is that the league operates on a completely different level than the most common fantasy formats. Those are 12-team redraft with roto or head-to-head scoring. There are also dynasty leagues with similar dynamics to these more common formats. Participants in these leagues can use existing resources for redraft leagues with a little mental tinkering. The norms of the industry still apply in a general sense even if there are some specific quirks.
