Atlanta is 2-0 with a pair of road wins. But before rushing off to claim how good the Hawks have become, do realize a couple of things: Those victories have been against winless Memphis and winless Chicago, who right now is the worst team in the NBA. Trae Young is shooting 55.6 percent from the floor. Young is an emerging superstar, but he's not nearly that accurate from the floor. He shot 43.7 percent last season from the field. 
The Pistons should have defeated the Cavaliers in their last game this past Saturday, but lost in double-overtime after leading by eight with three minutes left. 
Detroit has enjoyed recent success against Atlanta. The Pistons are 4-2 in their last six games against the Hawks, including winning the most recent time. That was a 136-103 blowout victory in Atlanta last January. 
The Hawks have a number of injured players, including center Clint Capela. Atlanta plays at the Nets on Wednesday. So it's not inconceivable that the Hawks may be looking past the Pistons to a much bigger game. The Hawks aren't good enough to do that and cover a spread this large.
