Street has been active a lot so the coaches have to see something in him. Sunday would be an excellent time for him to break out because Weeden needs to complete some passes, and as long as they are both out there on the field they might as well get something started. Eight weeks until Tony is back, maybe more, and it's hard to say when Dez will be back. Witten will be hobbling around and the new guy doesn't know the offense yet, but he'll learn.
Really Devin, it's probably now or never. If you don't pick up the slack, they are going to find somebody who will. Last call coming soon.
