It makes perfect sense for Williams to be practicing given that Stewart has not exactly been the definition of healthy and at least I remember back to 2005 when we lost the championship game in large part to having no running game and being so one dimensional. Both the starter and the backups were hurt.
Truth is that if Williams is named the starter it will largely be in name only. Stewart has been playing very well and has made some tough yards when we needed it. Stewart will get the majority of carries in any case. And that is really the issue, who will play the majority of the time nor who starts.
But don't let me try to add any logic to this chicken little scenario where the sky is falling. Carry on.................
The problem is you're not using any logic. When have you ever seen this coaching staff stick with the hot hand? I'll give you a hint. The answer is never.
