Nkemdiche most likely. Probably the same maturity issues as Humphries last year.
Id also guess: Harlan Miller. Possibly Marqui Christian.
Chandler - I dont think so. He has a very goofy personality, but CC and Golden have both praised his work ethic in practice, so I doubt its him.
Doubtful. RN is a laid back dude. He might not be hustling as much as he should but I don't think he is causing any issues. Especially since he's only played in one game. He didn't play in Buffalo where they had the melt down. He played against TB when we blew them out.
