While I think the Texans should/will take Bush, I can't say I'd be totally shocked if they take Williams. With that said, if the Texans take Williams, I would bet the Saints would take him and hold him hostage, eventually trading him for a king's ransom (probably to San Francisco).
I just feel this whole transcript thing may scupper Bushs' chances , and yeah I'm sure NO would do that too and end up with D'Brick
