Impact of Lions' O-line signings

From 2012 to 2013, the Detroit Lions only returned two veteran starters on their offensive line -- LG Rob Sims and C Dominic Raiola -- so close attention has been paid to their actions in that position group this offseason. 2012 first-rounder Riley Reiff moved over to LT, the team drafted Larry Warford to hopefully take over the RG slot, and the RT opening will be filled by the winner of a duel between Jason Fox and Corey Hilliard. This week, however, they gave themselves some other options.
