Reggie Bush barely slept Tuesday night.

The speedy, agile running back and celebrity figure said he only slept for about two hours because he was thinking about his Wednesday meeting with the Lions brass and all the ways in which he'd fit in the team's offense.

"It almost seemed too perfect," Bush said.

A perfect fit and a perfect pitch helped Bush sign a four-year, $16 million contract with the Lions on Wednesday.

And while the Lions' biggest free-agency splash was on offense, they made a concerted effort to improve last year's defense, signing safety Glover Quin and defensive end Jason Jones and re-signing top cornerback Chris Houston. There was also a report that free agent safety Louis Delmas may end up re-signing with Detroit.

Detroit was Bush's first visit after free agency opened Tuesday at 4 p.m., and he spent hours at the team facility in Allen Park before being introduced wearing a Lions cap and cream-colored jacket at a 2 p.m. news conference.

"It's like I got drafted all over again," Bush said. "I'm excited to be here. I'm excited to get this thing on the road and get to work because I think it's going to be a good thing, and I look forward to winning a lot of football games here."
