It's simple, really; in the last game, the offensive line was eventually overwhelmed by the KC pass rush, resulting in progressively worse QB play for Oakland. That line was back-ups for back-ups for back-ups, for the most part. This week, however, we have pretty much the projected starting lineup for the offensive line for the beginning of the season back on the field, and they played pretty well last week. I expect that there will be better running lanes; although I don't expect that we will run wild, I do think that we will at least be able to keep the Chiefs from teeing off and simply rushing the passer as they did before. This will help the OL, as will McGloin's style of play.
I am not saying that McGloin will be, or is, the long-term answer, although I do believe that he has shown that he can be a viable back-up at the least. What I do mean by 'his style of play' is that he is quicker to make reads, make decisions, and get rid of the ball, which should help prevent taking a lot of sacks. The requirement to that is that he has to make good decisions, and not ones that will result in turnovers, which will simply make things worse. The WR corps is playing better than it was during the game in KC; they don't need to be outstanding, just effective, which they have shown signs of being able to do.
If we can actually run a balanced offense, and move the ball with some efficiency, then the defense will hopefully be able to draw on that and not get worn out over the course of the game, since we just do not have that much depth (and that is not a failure of the GM or coach; it is a result of having cleared out so much cap space for next year. One step at a time...). If we can get an upper hand on TOP with some balance, I absolutely believe that we can win this game.
I would love to see the reaction to that by the squawking heads...
