ALLEN PARK — Coach Jim Schwartz said today he knows which quarterback will start the preseason opener on Saturday against the Atlanta Falcons at Ford Field.
  He said not to read too much into that.
 He also said he wouldn’t share the name. Schwartz said he hasn’t talked to Matthew Stafford and Daunte Culpepper about it yet.
   The coach said he’ll probably let each get in for a certain number of plays. But he won’t reveal his plan before the game because it could change during the game.
