1450 yards combined with 6-7 TDs is nothing that cannot be replaced with a 4th round RB from Boston. So a 2nd for CJ with another mod round pick sounds like a steal to me.
and usually I'm one of the ones that battles for keeping good players.
Just don't think he's anything special because he can't do it every down, he's always nicked up, and he's in a contract year and at the age of 28, he's not worth resigning for a big contract. So therefor, get something for him while you can or your gonna let him walk just like Byrd for nothing.
