From this article on NFL.com:  http://www.nfl.com/news/story/09000d5d81d5cfe2/article/bush-on-tenure-running-texans-defense-it-just-didnt-work-out?module=HP_headlines

Bush admits that he is done in Houston.  His excuses, however, are beyond lame.  No details, just generic ramblings.  Bush says, "A lot of different things (went wrong)," he said. "We gave up plays that we probably should have made, and we lost some games in the end that were tough emotionally on our kids.  "We still feel good about our approach. It just didn't work out."

We STILL FEEL GOOD about our approach?!?

WHY?!

What on EARTH is there to feel good about?

YOUR APPROACH took a solid defense and UTTERLY OBLITERATED IT!

YOUR APPROACH produced the one of the worst defenses in NFL HISTORY.

Good Riddance!
