Look, I think it's a bit premature to call for someone to be benched (Martinez, Fisher, etc.) because it's not ideal to sack someone, who has played well overall, just because of one bad night. I feel when they are the no-brainer starter all year, and then they totally suck, you have to give them a chance to respond. See if they are disappointed in their performance and come out to play with a chip on their shoulder the next week. But if we don't see big turnaround in gameplay, changes need to be made.
As for Tim Beck, he needed a week like last week. A game where even if he calls the perfect game we might lose, but instead he made multiple questionable decisions and has thus been berated by media and fans. He is still learning, and hopefully this was a big learning experience for him. Let's see if he comes out this week and "dance's with the one that brought him" to turn a phrase. By that I mean: run the GD football.
My two cents. Sorry if this has been thoroughly discussed elsewhere.
