The Rams will hold an open competition at left guard in training camp. It's a potentially huge trouble spot for a line already among the league's worst at the other four positions. "We've got a lot of options, and we'll continue to rotate guys in there," said coach Jeff Fisher. Options include former practice squad player Bryan Mattison, undersized center Tim Barnes, ex-Jet special teamer Rob Turner, and mammoth rookie project Rokevious Watkins.
