The voice of the Celtics, and birthday boy, Sean Grande joined The Drive Friday afternoon.

Grande preached that patience must be a virtue for Celtics fans in the early part of the upcoming season, especially while the team navigates the competition without PG Kemba Walker.

Walker is set to be out until at least mid-January as he rehabs his injured knee.
