It's a "revenge game" for the Bulls for whatever that's worth.
The Bulls will probably smoke them but I think they are still a mediocre team at best. Shouldn't be favored over anyone on the road, especially a defensive team. Garnett may still want to get out of Minny some day and Chicago would be a perfect fit. Bull's using fat man Sweetney inside a lot more these days. Garnett will abuse the Bulls inside defense, and not just by scoring himself.
