Their presence on the Bulls' staff is exactly what Vinny needs in his first season as a coach -- mentors who can help him navigate the coaching waters.
Many times it's difficult for teams to get permission to even talk with veteran coaches who are under contract. When I was putting together a staff in SAC, veteran coaches (and guys I'd worked with in the past and really respect) like Tom Thibodeau, Tom Sterner, Keith Smart, and Hank Egan were off-limits.
To get Bernie (at 64) and Del (at 71) is a coup for Vinny and will make his rookie coaching season considerably smoother .
