The defense, despite all the injuries, are still at least OK. Bill shows his value there by helping that unit weather the storm despite the issues.
The offense is just a wreck and I don't blame BOB. The playcalling looked good early, but the execution was up and down. When Mac looked like he was teetering on turnover territory, they started turtling and going back to the safe screens to keep him from blowing it. Obviously there have been injuries here as well, and they aren't the most talented unit in the first place, but man they should be better than this.
Mac has the tools and he shows flashes at times but I find it hard not to place the blame on him most of the time. I don't really have reason to think Zappe or Grier would be better, but I've really just grown tired of watching this song and dance. Even if they still lose, at least it'd be a half season of losing differently and you could maybe hope for some progression from the next guy over time.
