This is actually a strategy for any of the daily contest games - including Snapdraft, FantasySportsLive, and Fanduel. There are at least three reasons to make (or review) your picks as late as possible:
1. Take advantage of late breaking news. If there's an injury or other late breaking news, you can target players who will benefit from it, and avoid those who will be harmed.
2. Make sure your players in the lineup. In particular, you can check lineups for early games. That alone is reason to slightly favor players (especially catchers and others who get frequent off days) in the earliest set of games.
3. Check the weather. Weather forecasts have a tendency to shift dramatically throughout the day. Sometimes a game that looks to have decent weather in the morning forecast will become a clear rainout risk by game time.
