Diarra probably wants the chance to start and be a vocal captain. And expressed what he wants to get out of next season to prepare him for a chance to play pro ball, somewhere.
Hurley probably wanted Diarra to understand the mix of players they were targeting to bring in that could see time at PG, including Nowell and Mahaney.
