Over the weekend, I made visits to three California gyms to watch workouts -- one in Santa Monica, another in Reseda and a third in Oakland on Saturday.

The three workouts were all different. Over 80 general managers and NBA scouts attended a group workout for the Wasserman group on Friday morning. The workout was headlined by Terrence Jones, Fab Melo and Tony Wroten Jr. The workout was drill-oriented and didn't involve any actual competition.

On Friday afternoon, I was in the 360 gym to watch trainer Joe Abunassar work out his clients -- Terrence Ross, Arnett Moultrie, Jet Chang and Terrell Stoglin. After the workout, I was able to see the top prospects compete in some competitive four-on-four action alongside and against NBA players Austin Daye and Rasual Butler.

On Saturday, Aaron Goodwin invited me to Oakland to watch a grueling private workout for Damian Lillard.

Here's what I learned:

• If the draft plays out the way we expect it to, nine of the top 10 players in the draft will come from five of the biggest programs in college basketball -- Kentucky, UConn, North Carolina, Kansas and Baylor.
