These games are being played in Las Vegas as part of a Summer scouting event with college coaches observing. They are being shown on one of the ESPN channels.
I don't know anything about the officials. They may be working as part of a camp. I know several of the local guys and didn't recognize any of the people working while watching a couple of contests.
