Who should I trade?.?

Do you need Tomlinson that badly? I say no - you have 3 decent starters at RB already. And Tomlinson won't be that productive every week - don't overvalue him after 1 game against the porous Bills. I drafted the Cowboys defense (their terrible) and have been going with a new D every week now. Just pick the best available D against the worst offense every week. Relax, it's a long season and their are bound to be injuries, flukes and such.
