GRAND BLANC — It’s probably going to be another month before coach Jim Schwartz names his starting quarterback. That is, unless Daunte Culpepper or Matthew Stafford steps up and makes the job his during the first few weeks of training camp which starts Saturday.
 Schwartz’s plan — of sorts — is to split the training camp reps three ways between his quarterbacks including Drew Stanton.
 “You’ll probably see almost even reps through (training camp). You’ll see different guys start off different drills,’’ Schwartz said. “Go ahead and try to have fun reading between the lines with that because you’re not going to be able to,’’ Schwartz said today almost defying the media to draw up an early depth chart.
  If no one wins it sooner, he would like to know who will start around the time of the fourth preseason game which is Sept. 3 at Buffalo.
  The season opens Sept. 13 at New Orleans.
