Jason La Canfora of CBS Sports reports that the Seahawks and Eagles have been two of the more aggressive teams in the trade market the past few years and are still hopeful of upgrading their left tackle positions before Tuesday trade deadline. According to La Canfora, the Seahawks have made their desire to add a tackle known and have explored trades for Bills LT Cordy Glenn and Texans LT Duane Brown in recent weeks. La Canfora says that Glenn isn’t an option for them due to cap restraints, but Browns still a possibility. As for the Eagles, La Canfora mentions that they began identifying possible trade replacements for injured LT Jason Peters shortly after he was lost for the season during Monday’s game.
