Drew Brees endorses Aaron Glenn as his top pick and Klint Kubiak as his in-house hire

Much closer to few than almost everyone of SP’s coaches. There’s Campbell and Glenn. Then there’s Pete, DA, Joe Lombardi, Marrone, and Kromer who didn’t have success as lead position coaches/HCs/OCs without SP.

Jahri Evans and Brunell are his former players turned coaches but didn’t begin their coaching careers directly under Payton

Yes. Payton's tree isn't great outside of Campbell and Glenn. I think probably mostly because Pete remained his OC for so long. He didn't want HC jobs so no OCs ever developed under him that moved on to HC jobs.
