Defense is a problem because collectively the Hornets are slow and frail bodied. They also lack basketball instincts. Rivers, and Davis are young, Lopez, Smith, and Anderson play hard, but everyone else, including Aminu, and especially Roberts, who is just terrible on defense, are inept. I know coaching plays a role, but some players are just not very bright and require simple sets, and easy assignments on both ends of the floor. Monty may want to play like the Spurs, but his players lack the aptitude, collectively, to do so.
