RB in the draft for Detroit?

Given the Detroit Lions' myriad needs on the defensive side of the ball -- as we've repeatedly noted in this space, they have six starters from 2012 hitting unrestricted free agency, in addition to having released veteran DE Kyle Vanden Bosch already -- one would think they'd focus on that side of the ball in free agency and the draft. And they very well may choose a player on the D-line at No. 5 overall; there should be several really good ones from which to choose. However, in Round 2 and after, their focus may shift back to offense.
