Anthony Davis and Austin Rivers began their first full day as pros together on Hornets owner Tom Benson’s private plane. They flew from New Jersey to New Orleans, where the two 19-year-olds will be expected to ignite the turnaround of an NBA franchise before they’re even old enough to participate fully in the Big Easy’s renowned night life. They aren’t giving themselves much time to party anyway. Their plan is to remain in New Orleans and work out together at the Hornets’ training center until Davis, the top pick in Thursday night’s draft, has to leave for Team USA tryouts on July 5. If there’s time, they might even find places to live.
