Either way you're not fairing out so well. Here's why:
Doug Baldwin has hope for a good future but with Rice back to full strength and Mike Williams feeling better, Baldwins production will decline. Also the Seahawks are playing the Giants and I would imagine that Tavaris Jackson will have a rough outing.
Jones isn't a very good WR and he's proven that when Andre Johnson went down last year and the year before. Owen Daniels will likely be the go to guy against Oakland. I, however, would start Jones over Baldwin because the simple fact Andre Johnson is out and Oaklands defense isn't very good so Jones will see an increase in production but not a huge increase especially with Foster back. Foster will carry the load for the Texans.
