Rookie at RG for Detroit?

The Detroit Lions feel pretty good about their franchise QB, as they doled out another massive multi-year contract to Matthew Stafford this summer. Likewise, Stafford's primary target Calvin Johnson was the recipient of a huge contract last offseason. When it comes to the gentlemen on the O-line -- who make all those gaudy stats possible -- that confidence isn't quite there. The team has done some re-tooling at a few spots up front (they'll have a new starting LT, RG and RT this season), and in the case of RG, it may well be a rookie positioned there.
