Look, it's no hate on Pop, I still think Phil was better. Sure, Phil had extremely talented rosters, but managing those egos, threepeated 3 times, and went back to back the other time, just really impressive, and he got that done in 20 seasons. Think about it this way: as a coach, he had more seasons winning a championship than seasons he did not win a championship. That's more than just pure luck, IMO.
And yes, he's a terrible GM/Manager.
