I just finished the collage feeder season and got the same error that I got before. I followed redsoxford instructions and found that it is a newly created 18 year old, Armande Green, that for some reason is on the DFA. I then did a search in game for the player, and used the Action menu on his player page to move him to the active roster, ending this problem. It is a bug that newly created player(s) are going to DFA when you as a manager can't easily in game fix this.
Thanks redsoxford, and Nutlaw for the help. At least now I can work around this.
