The 7-13 Spurs probably are the most disappointing team in the NBA at this juncture. But unlike the Warriors, the Spurs still maintain All-Stars in LaMarcus Aldridge and DeMar DeRozan. I'm not ready to close the book on any team with that talent especially one coached by Gregg Popovich. 
The Spurs showed they aren't dead by haltiing the Clippers' seven-game win streak, 107-97, on Friday. The Clippers are a top-five team. That should give the Spurs a much needed jolt of confidence. 
This is San Antonio's lone road game during a seven-game stretch. The Rockets are up next for the Spurs - and that's a probable loss. So San Antonio should be focused for this matchup. It's a big step down from the Clippers. The Pistons are seven games below .500 and that's having played only one Western Conference opponent so far, the Timberwolves. 
Detroit has two stars, too, in Andre Drummond and Blake Griffin. But I would take the rest of the Spurs' lineup against the Pistons. 
The Spurs hold a winning record versus sub .500 opponents and have covered seven of the last nine times versus Detroit.
