Yep, no such thing as a lock, but this one comes pretty close.
On one hand, you have the home team that has lost only a handful of games there all year, SA's been getting favorable treatment from the officials and they do have two individual players that can put together superhuman performances.
But Detroit has pounded these guys in the last four games, losing only the close one when Horry put up that phenomenal 2nd half in game 5. The Pistons took away their shooting spots, then they took away their passing lanes. Detroit is the only team on the court that can get a fast break and they've been doing it more and more each game. And the Pistons execute screens and they run plays that work even when the Spurs know whats coming, while the Spurs appear to be ad-libbing the entire game.
I'm tempted to take the moneyline because it looks to me like the wrong team is favored, but I'll go ahead and take the points and up my risk factor instead. It's possible something can go wrong (see officials) but if the Spurs win I can't see them doing it by more than 4 points.
