If Dunta isn't signed by this time next week, then you can fret (if you must). Until then, remember that the Texans have a spotless record in signing their draft choices prior to training camp. If any organization in the NFL (heck, pro sports) deserves the benifit of doubt in this regard, it's the Texans.
Is that really "our Vinny's" question about Carr? I just don't see him giving a hoot what McClain thinks.
