Martin Mayhew enters this season with the Detroit Lions feeling a sense of urgency.

"Let me just say this," Mayhew said.

"When you win four games, you better have a sense of urgency about it. Certainly, I had a great sense of urgency about this offseason, but I wouldn't categorize it as not having a great sense of urgency in the previous offseasons. I just think we came into it with a great sense of urgency about getting better."

The Lions have one winning season in four years since Mayhew took over the full-time general manager role.
