I think the entire Bridgewater drama was simply a little gamesmanship.
The idea that a guy who hasn't taken a snap in an NFL game since 2015 would take over from a guy who has his team at 7-2 and threw a bunch of TDs this past week is ludicrous.
Zimmer is way too old school to pull that stunt.
Keenum is no push over. He'll get the ball out fast and accurately. But, he will turn the ball over (I think he had 2 INTs last week). And, while he is mobile, he's not Russell Wilson. He's not fast, he's not quick, and our fast D ought to be able to pin their ears back and go after him because of our D athleticism.
Important the Rams make them one dimensional. Take away the passing game and make them beat you with the run. Don't think Minny can do that.
