Why don't the Browns try something new?

It seems that the browns can't find an answer on offense. They don't have a number 1 receiver, a running back or a line. Colt is running for his life every time he touches the the ball. He has no pocket to pass from and even when he gets the ball away no one is there to catch it. It seems that this west coast offense is not working for the Browns at all. I think it is time to try a new approach before we really embarrass ourselves on national T.V. We need to go back to the offense we had last year. Now i know that Payton is out but maybe we can use the backs we have. The line is terrible too but since Steinbach went down but maybe we just need Shurmur to kick them in the ass. We have a quarterback I think? He just needs time in the pocket to find a receiver to throw too. Hopefully next year we will get the tools we need to make this team somewhat  descent.
