The Bucks have long been an odd bugaboo to the Spurs. In the Duncan era (1997-present), the Spurs are well-above .500 in their head-to-head matchups with just about every team in the league. In fact, with this year's games added in, there are only 7 teams that are even within 10 games of .500 in those matchups:
1. Cleveland 15-11
2. Dallas 30-23
3. Detroit 15-10
4. LA Lakers 25-24
5. Philadelphia 17-9
6. Phoenix 28-22
Of course, the 7th is Milwaukee -- since 1997-98, the Spurs are 12-12 against the Bucks and needed to sweep them last year just to get back to .500 in that span.
If the Spurs win at home against MIL, they will be over .500 against every team in the league since Tim Duncan's first game. That would obviously be a claim that no other club could make (since each of them would be under .500 against at least 1 team).
