I just don't see any way how they don't try and pick up the tempo of the offense. After the Atlanta game I know Fisher said they'll stick with what they were doing and not do the whole no huddle/spread scheme, but then in Dallas they got creamed and couldn't move the ball, and when they did the clock was just bleeding all over the field.
I'll be really surprised if they don't go to a hurry up look a few times early. Maybe not from opening drive to final whistle, but I hope for damn sure we see a little more sense of urgency on offense. I really believe Sam has performed admirably. He could have made some better decisions or taken more chances, but like X has echoed a few times, if the execution by other members of the offense was up to par (i.e. drops/blocking/routes) it wouldn't be as much of an issue.
Defense will have to sort itself out, those guys know how to play and did it at a high level last year, but the offense needs a spark.
