Zero chance the Texans draft both those guys even without Romo.
If they do get Romo, don't be surprised when they don't take a QB until round 4 or later. If they get Romo, they're going to go all in on trying to win it with him, and picking a QB high when they've left these other needs unaddressed isn't going to help that cause.
Of course, but this is pure fantasical speculation in this thread/forum. Texans ain't gonna take any of our advice, so why not have fun with it periodically?
