I hate Jackson, so it pains me to do this. However, if we're going to say that Jackson is a beneficiary from coaching great players, we also have to say that same thing about Red as a coach. He doesn't win his 9 titles as coach without Bill Russell, Bob Cousy, Hondo Havlicek and literally a stable of many other Hall of Famers.
Now that's not to say that Red didn't bring a lot more to the Celtic organization than Jackson ever brought to the Bulls or Lakers: he did. However, that was Red the GM/President, not Red the coach.
So in summary, I hate Phil; however, it's not like Red coached the '95 Celtics to 9 NBA titles either.
