If Denny Green is down on L.J. and his days are numbered then I think the Cards should look to trade the LT. One potential good trade would be to send Shelton to the Chargers for holdout center Jason Ball and guard Toniu Fonoti. Ball is an exclusive rights free agent who has burned bridges with the front office over his contract. Fonoti is a backup guard who came out early a couple of seasons ago and hasn't stayed healthy and has lacked maturity but has athletic ability. Ball is a very good center who could solidfy that position and allow Green to move Stepanovich to right guard. Here would be the line for the Cards and the starting line for the Chargers:
Cardinals
LT-Davis, LG-Wells, C-Ball, RG-Stepanovich, RT-Clement
Backups: Lindsay, Leckey, Roundtree, Spikes, and Fonoti
Chargers
LT-Shelton, LG-Oben, C-Hardwick, RG-Goff, RT-Van Buren
Cardinals
LT-Davis, LG-Wells, C-Ball, RG-Stepanovich, RT-Clement
Backups: Lindsay, Leckey, Roundtree, Spikes, and Fonoti
Chargers
LT-Shelton, LG-Oben, C-Hardwick, RG-Goff, RT-Van Buren
