Jackson is a very good coach. You can't take that away from him. He took teams that were good but not winning titles and got them to win titles. In terms of coaching, it would be hard to argue that Jackson isn't one of the best ever as is of course Red (other than Red, hard to think of say 5 better coaches ever than Jackson). The difference though and the reason that you can't really compare Phil to Red is that Red did it all. Coached teams to titles like Phil but also scouted, drafted, traded, etc. Different era but Red did so much it is really hard to believe. Celtics fans get this but many don't and it isn't worth arguing with those who don't.
