Another version of that system will be used at the G-League Winter Showcase in Vegas. They are going to copy the All Star game and set a target score for the 4th quarter.
At the start of the 4th quarter the game clock is shut off. A target score is set and whichever team hits it first will be the winner. Sounds like they will take the leading teams score at the end of the 3rd quarter and add 24 points to it. That is the target score.
Another announcement. The Ignite Team (The team where the draft prospects play) will play a full 50 game schedule this year.
