PostLck (Post-Lock) Projection Tracking: This is a % difference vs. the pre-lock projection that tracks the changes throughout the duration of the slate. This projection adjusts for new information that becomes available after the lineup lock, such as late-breaking news on player injuries, starters, or other factors that could affect performance.
The ability to track the percent change in projection (PostLck versus PreLck) is especially useful for strategies like late swapping, where you make changes to your lineup after the initial lock but before the games involving your swapped players start. This can be a crucial advantage in DFS contests, as it allows you to react to late news and potentially gain an edge over other participants who may not be monitoring changes or who have chosen not to make late swaps.
For example, if a player's PostLck projection significantly increases due to an unexpected event (like a starting player being scratched, leading to more playing time for a backup), you might decide to swap that player into your lineup to capitalize on the opportunity for higher fantasy points. Conversely, if a player's projection decreases (perhaps due to an unforeseen matchup change), you might swap them out to avoid the risk.
