If Reid leaves to go to another team when his contract is up this year, with the amount of money and play time he'd get, the Texans are likely to get a 3rd round compensatory pick next year. At 24, he'd likely be one of the top 3-4 safeties on the market, and definitely the top under 30. Even if you time discount it for a pick this year, that's a 4th, and nobody in their right mind will give a 4th for half a season of play.
