The Warriors beat the Pistons in Detroit, 116-106, back on Dec. 29 achieving the victory despite not having Draymond Green, their second-best player. Golden State has improved since then with Green back in the lineup going 8-7 since defeating Detroit. 
The Pistons couldn't stop Stephen Curry and Andrew Wiggins, who combined for 58 points in the win. Curry leads the NBA in 3-pointers. The Pistons rank 26th in 3-point defense. So Curry and Wiggins could be in line for big games again. 
Detroit upset both the 76ers and Lakers this week. Both victories came at home. The Pistons caught the 76ers minus Joel Embiid and the Lakers without Anthony Davis. This isn't to downplay the Pistons' upset wins. They were impressive. The 107-92 smashing of the Lakers came just two days ago. 
I doubt the Pistons play nearly that well in this spot following that hugely-satisfying home win. Detroit has lost its past three road games, including its last one to the Cavaliers, 122-107, this past Wednesday. This marks Detroit's fourth game in six days. 
The Warriors should be motivated after a flat performance in a 114-93 road loss to the Suns this past Thursday. Golden State has covered the past five times hosting an opponent that has a losing road record.
