Something is off with Russ, and I'm not going to throw a bunch of stats out there to defend my point. As someone else in this thread mentioned, it's the eye test, and if you're viewing his play objectively, it should be pretty obvious. He's not the same QB he was early in the season, or even in seasons past. He seems to have lost some confidence, and has been very hesitant and indecisive ever since that stretch when he was turning the ball over a lot.
This is just a theory, but I wonder if he's being somewhat handcuffed by Pete who's instructing him to protect the ball at all costs and not to throw into any tight windows which may be causing the hesitation? This is just a guess on my part, and I have nothing to back that up with. All I know is he doesn't look like the same QB, and his decision-making has been very questionable at times. Something is causing him to second-guess himself on occasion, and I don't recall ever seeing that from him before. He has always been supremely confident in whatever he's doing.
Whatever the issue may be, I hope he finds his stride again before the playoffs get under way as we're going to need him to be at the top of his game.
