All reasons and excuses aside, deep down, I suspect you're right.
If history is any indication, we sign guys we want to keep before we get to this point (Brockers, Tavon, Foles, Ogletree, Barron) and we let guys who we don't want, but the fans assume we would want, walk: Trujo, Janoris, McLeod, Watkins. That would suggest Joyner is gone as well. (You'd think we would have done a contract with him by now, wouldn't you?)
Let's hope this isn't the case. But then again, I never thought we'd trade Dickerson or cut Bruce.
