We may never know how seriously the Texans truly are/were about signing Brock Osweiler. As you'd expect, there hasn't been a single word that's emanated from the organization itself about their interest in Osweiler. It's entirely possible the Texans have simply been used as leverage to increase the amount of money the Broncos pay. Given the nature of breathless free agency speculation and all the lying/exaggeration that accompanies it from various media outlets, it's all a guess.
Regardless, at this point, the tea leaves seem to indicate that the Texans' search for a quarterback won't end with them signing Osweiler. With the caveat that it's subject to change (especially if news breaks that Osweiler is on a plane to Houston), are there any other free agent quarterbacks you believe the Texans should turn their attention to?
UPDATE: The best part of posts like these is how they can be comically wrong yet immortalized forever. Your Houston Texans have signed Brock Osweiler.
