Less than a freaking minute after I publish this post, John McClain reports that your Houston Texans did in fact hit Dunta Robinson with the franchise tag. Stupid 24 hour news cycle.
As Dunta was not slapped with the exclusive franchise tag, he can technically negotiate with other teams, though the Texans have a right to match any offer and would receive two (2) first-round picks if Dunta left. Although I cannot see any team deciding that Dunta is worth two first-rounders, I ask you this...if you were Rick Smith and Dunta got an offer from another team, would you match it? Or would you snap up those two first-rounders? Such a scenario would probably never play out, of course, but I think you'd wish Dunta the best of luck and take those draft choices every time.
