NCAA basketball stats

I’ve looked for years for the +/- differential when players are on the floor and eventually gave up. My guess was the NCAA preferred not to keep track of individual stats like that. Tonight I heard the announcers say that the team was +9 with Brady on the floor and -20 with him off the floor after we made our second half run to tie the game. So that tells me the stat is out there. Does anyone know where it exists?

I thought they were talking about just that game, not overall.
