Yes, much like Satan, we have to be called up.
As to the original question, FF had his moments, surely. And I do think he has a cannon for an arm, is strong and not afraid to take a hit. He can also be a run threat at short distance.
But he has trouble making quick throwing decisions and I've seen no evidence he can read a defense, or react to a change by them as a play goes off. Some QBs have that ability to think "what if my primary is suddenly covered? Who will therefore be open now?" I don't think he has that crtitical skill.
