Since you like it so much, "you're an idiot".
However, I agree with you. JF's knee is so unstable that it seems like he is out. I haven't heard that BG is 100%. I heard he was cleared, but that isn't the same thing. Either way BG isn't real mobile, is injury prone and our o-line is porous, so its not a huge stretch to envision the #2 QB in there.
