The problem is that the original deadline prior to the last collective bargaining agreement was 2nd March. This changed when the CBA was re-worked and it appears that the NFLPA neglected to tell anyone that players wishing to void portions of contracts and therefore activate their right to free agency would need to do so earlier than was originally the case.
Dennis Northcutt at the Browns has had the same problem and there will be plenty of others.
My guess is that if the NFLPA holds it's hands up then TO etc will be able to test free agency anyway as the error is not theirs.
