At this point you have to hold onto CJ Anderson. Him turning his season around is just as likely as whatever scrub someone is willing to trade for him currently actually ends up helping your team, and there is more upside with Anderson.
Keep in mind he's played against two of the top 5 defenses against the run, was hurt early in game 1, had a short week to heal, and had Peyton Manning throwing like a middle-school-aged girl for the first 6 quarters he played. If Peyton can play like he did in the last two quarters last night that will open up the run game, plus now Anderson has extra time to heal up. Anderson's next four games are against a Suh-less Detroit, the recently torched by Carlos Hyde Vikings, then lol Raiders and lol Browns.
