It's actually pretty simple why Geno sucked tonight:
1) Geno was injured in a way that affected his throwing motion, an injury that was either concealed or that occurred in-game. Someone noted in another thread, that Howell was staying warmed up nearly the entire game, and Geno preferred throwing to one side. I apologize if any of this is incorrect; repeating what I read, which sounded plausible.
2) The announcers thought that DK ran his route wrong on that last pick, and didn't help his QB.
Still, Geno wasn't the reason we lost this game. Just like he wasn't the reason we lost the Giants game.
