One of the more interesting unrestricted free agents to watch in the next few weeks will be QB Daunte Culpepper. His contract with the Lions is done, kaput, finished. While Martin Mayhew, the Lions general manager, said not to count out a Culpepper return to Detroit, it seems highly unlikely. It’s not so much that the Lions wouldn’t want him, but I never got the feeling he was too happy with the Lions’ situation. Culpepper still sees himself as an NFL starter. In Detroit, he’s behind Matthew Stafford. He never had a good game — or a win — with the Lions but that wasn’t all exactly his fault. Still, he had opportunities and did not take advantage. That said, the Lions need a veteran backup quarterback in case Stafford is injured again. Drew Stanton will be back, but he’s not ready for that role.
