ALLEN PARK, Mich. (AP) - Matthew Stafford will be on the spot this year for the Detroit Lions, and the 26-year-old quarterback understands that. Stafford has put up some big numbers in his five seasons with the Lions, but he's taken them to the playoffs only once. After a late-season fade last year - with Stafford's turnovers a primary culprit - Detroit changed coaches, and the team seems to be going out of its way to try to surround its quarterback with what he needs to succeed. Jim Caldwell replaced Jim Schwartz as coach, giving Detroit an offensive-minded leader who has worked with Peyton Manning in the past. The Lions also hired Joe Lombardi as offensive coordinator. He worked with Drew Brees as an assistant in New Orleans.
