Speaking as a Panthers fan, I'd have to say that Williams, will start to pick up in the next few games. In Carolina's first two games GB and Arizona stacked the box (knowing that carolina's running game has been the only bright spot in the last few years) and tried to force Cam Newton to through the ball. Now that Cam has proven his ability to pass, and extend plays running the ball/taking off for a first down I expect Carolina's future opponent will decide to drop their linebackers back into coverage more often.
Williams will be dangerous, he can get yards in BIG chunks, I expect a big game out of him against Jacksonville next week. Only problem is splitting carries with Stewart. I'd stick it out for at least one more week.
I have knowhon, and am really hoping he gets healthy, but my hopes are not high, I'm trying to trade him as we speak.
Best of luck in your decision, please, help me out.
I own knowshon, but also have mcgahee as a backup. If you are going to attempt this, you need to make sure you get mcgahee too. If you cant afford to drop anyone for willis, I wouldnt go after knowshon.
