They do?
And who cares about the entire league. There are 3 (maybe 4) teams that matter in the East. (Boston, Miami, Orlando, Chicago) and 3 teams out West (SA, LA, Dallas) The rest is just junk to wannabes.
How do those team do against each other?
Glad you asked.
Boston is 8-4: 1-0 vs Spurs, 0-2 vs Mavs, 1-1 vs LA, 3-0 vs heatles, 1-1 vs Bulls, and 2-1 vs Magic (who don't deserve to be in this list IMO).
Heatles are 3-6: 0-0 Spurs, 0-2 Mavs, 1-0 LA, 0-3 Celts, 0-1 Bulls, 2-1 Magic

LA is 2-7: 0-2 Spurs, 0-1 Mavs, 1-1 Celts, 0-1 heatles, 1-1 Bulls, 0-1 Magic (only reason they belong on this list is the B2B titles)
