I don't buy any kind of lingering injury. With rib injuries, particularly ones bad enough that it hurts to breathe, you see indications in how people move, walk, run etc.. Fitz threw the same (motion wise), and not only did he run the same and just as often, he did not slide but went in head first and drove for additional yards. QBs with rib injuries would NOT do this. Not even IronMan FitzMagic.
