You see a lot of teams stinking it up in the preseason and then come out and play much, much better when the regular season arrives. And I've become convinced it is NOT because of a lack of intensity, but because most teams are really that thin. You've got starters...and everyone else. And when you get enough of those "everyone elses" playing at the same time, it can look like a totally different team. Most teams are exactly one-level deep in terms of starter quality. We lose one OL, bam, all of the sudden we're looking at a guy like McQuistan playing out of position. And I can think of four more positions right off the top of my head where if we lose one guy, we're totally screwed.
Imagine if we lost Romo, Owens, Barber or Witten? There would be no hiding those losses. Again, true depth is such a pipe dream. Not just for us, but for most.
