This is our patented feature that allows you to replace your players during a game. No other site offers this feature, nor will they be able to in the future. The system is designed using the 60 minute game clock. For example, if you replace a player that played 7 minutes in the first quarter with a player whose game has not yet started, the replacement player will not start accumulating points until after 7 minutes in the first quarter have passed. This feature is completely customizable. You can control how long to wait in between swaps, or how many swaps can take place during a game week. You can also turn it off completely if you choose to for your league.
