Most of the time it has to do with a player's spot on the depth chart as is the case with Munir. I have heard quite a few other names but I'm not going into any detail on them untill one or more of them actually takes that step and then even if they were to I wouldn't mention any other names because I don't want to start or contribute to a firestorm of rumors that may or may not turn out to happen, plus I think that would be very irresponsible of me as a member of the staff to release such a list without very solid confirmation.
