Why do they need to announce it?
Its right in the game manual:
In addition, there will two options available following the All-Star break for 10 scouting points each:
Scouting Combine: Every player in the upcoming draft class will show up to be measured. You can send a scout to the combine to learn the ages and heights of all 48 players in the upcoming draft class.
Group Demonstration: In order to help get their names out there, all of the players your scout estimated to be 1-ball or 2-ball prospects have offered to arrange a demonstration of their skills. This option is equivalent to scouting each of these players once, though it will not provide any additional information for players you have already scouted.
Given the allstar break haven't happened, it isn't available
