Since we're locked in on quarterbacks today, we might as well continue around the horn. In Detroit, coach Jim Schwartz said it's unlikely he'll declare a winner this week in the derby between Daunte Culpepper and Matthew Stafford. Schwartz continued to hint at the possibility that he'll extend the competition into the final week of the preseason and implied he might not make his decision public until the Sept. 13 opener at New Orleans.
Schwartz: "... From our standpoint, there may be even a point where we make a decision on a quarterback and we may not even announce it. What good does it do? Understand from our standpoint with the Lions is, there is a team down in New Orleans that's getting ready to play us and if they can zero in on one quarterback, it makes it a little easier for them to plan. If they have to prepare for both, then Daunte and Matthew both have a different skill set. They are both a little bit different the way you would game plan them. Most likely we're trying to keep that a little close to the vest."
Groan. I'm always confused when teams believe they gain a competitive advantage by keeping the identity of their starting quarterback a secret. Let's put it this way: If it isn't obvious by performance who your starting quarterback is, then you've got problems that can't be smoothed over by a game-day surprise.
