Matthew Stafford has won the Detroit Lions starting quarterback job over Daunte Culpepper. "I've had a lot of very tough decisions in the last few days ? guys making the 53-man roster or not making it ? but none more difficult than at quarterback," said Jim Schwartz. "We announced to our team this morning that Matt Stafford is going to be our starting quarterback." Schwartz felt Stafford and Culpepper played well in training camp and the preseason, as did third-stringer Drew Stanton before sustaining a knee injury. "I'm very, very comfortable with the quarterback position here, not just one and two, but also three," Schwartz said. "What made this decision difficult was that I think we can win with Daunte Culpepper, I think we can with Matt Stafford, and I think we can win with Drew Stanton." One of the factors that helped Schwartz make his decision was the 21-year-old rookie's chemistry with Detroit's biggest offensive weapon, Calvin Johnson. "I think he had 15 snaps in the preseason with Calvin, and you could already see what was possible there," Schwartz said. "The big plays were always there."
