I also have Charles and am in a position where I need to decide if I want to keep him or let him go. I keep two between CJ2K, Charles and Gronkowski. Right now, I am keeping CJ2K but my second keeper is still up in the air. Thoughts? I think Charles can rebound nicely, but, the thought of Hillis stealing goal-line carries worries me a bit.
I start the standard 2RB, 2WR, TE, Flex. Non-PPR, 10 man.
I am more concerned about Charles' health than losing carries but in your position, I would keep Gronkowski (he is a top receiver in the game but can be in the limited TE position) and decide between Chris Johnson and Charles. I am a Titans fan and no so high on Johnson. Charles and Johnson are probably equal in upside and risk. Probably flip-a-coin close but if Charles is healthy, I would take him over Johnson.
The Titans offense is moving toward a hybrid run and shoot with the new coaching staff and are putting a premium on a running back who can catch out of the backfield and pass protect/block and Chris Johnson is poor/below average in both those areas. Titans will not give up on him (his contract is too huge) but a healthy Ringer fits the offense better, so I suspect a possible 60/40 might develop (Johnson's running style would fitwell with that and he would put up good numbers in a 60/40 probably. )
