There's an old Irish saying that if you want to climb a wall, first throw your hat over. Then, you're committed to trying to recover it.
The Cowboys have taken a similar move today, releasing safety Gerald Sensabaugh, a starter the last four years, providing a baseline of unspectacular play. He was better than many of the alternatives the team has tried in the last decade, but that's faint praise.
Dallas has needed a quality safety or two for years, and now the Cowboys have forced themselves to improve the position. The projected starters as of this minute are Barry Church, he of the re-habbing Achilles tendon, and Matt Johnson, whose tricky hamstring scuttled his 2012 campaign.
Will Dallas add to the position in free agency, in the draft, or in both? Start scanning the available safety candidates from both pools. Jerry Jones has tossed his cap over the wall.
