Isn't he the Triangle man? He's retired now. Phil might want a system but maybe not necessarily the triangle but a system with Red's core principles

Phil has learned a lot about the Triangle over the last 20+ years. You could say he now has a Black Belt in the Triangle offense. Tex is 92 and has dementia. Trust me Phil can teach the Triangle and if he hires one of his old players like Kerr, he'll be able to teach it too. It's actually a very simple offense that leads to a lot of options off a very basic set.
