Where are you hearing this? If on sports talk radio, callers tend to be very unsophisticated, reactionary and completely unable to see the big picture.
Jones is signed through next season and the only talk I've heard is whether he should get a new contract. Of course, contracts are not guaranteed in the NFL, but cutting Jones would have huge salary cap implications and trades in the NFL are pretty rare these days.
Much of this is due to Matt Ryan eating up so much of the Falcon's cap space. I don't blame the front office for that as it is pretty much required after a QB has a career season, but it did really hamper the ability to build a defense.
