How many current nba players went to USC?

As of my knowledge cutoff in September 2021, there are three current NBA players who went to the University of Southern California (USC):

1. DeMar DeRozan (Chicago Bulls)

2. Nikola Vucevic (Chicago Bulls)

3. Evan Mobley (Cleveland Cavaliers)

Please note that this information may be outdated as player rosters can change over time. I recommend checking the official NBA website or other reputable sources for the most up-to-date information on current NBA players and their college affiliations.
