It appears to be an addiction, sure. Lions coach Jim Schwartz once — jokingly, he swears — likened his own obsession with Jahvid Best's highlight films to others' watching porn. And it was with great satisfaction that Schwartz and his offensive coordinator, Scott Linehan, celebrated the team's 2010 draft-day trade to acquire the dynamic running back out of California. At the time, Schwartz even recalled a dinner conversation with Linehan from months earlier, "He said, 'Man, what I would do for a running back like that. That guy is everything we're looking for.'" Of course, 18 months later, Best's career was effectively over and the Lions — along with their long-suffering fans — found themselves looking for another fix. Wednesday, the team happily announced it'd found it, introducing newly signed running back Reggie Bush, the No. 1 target for the Lions and arguably the biggest free-agent signing they've made since … well, I'm not sure, but it's been awhile. (Damien Woody? James Stewart? Scott Mitchell?) You can feel free to argue that last part. And many certainly are debating the merits of the first part, as the Lions targeted a running back ahead of some other needs, though admittedly the secondary got a huge boost with safety Glover Quin joining Chris Houston and perhaps Louis Delmas, as well. But there's no denying this point: With Bush signed, the Lions have to do more than just tease their fans with highlights this time.
