The Houston Chronicle took a good look at the situation on Monday, noting that negotiations will be tricky. Schaub recently said that he didn't know whether his agent was involved in long-term talks with the team. That's his polite way of saying: "I don't want to talk about it."
There are a few reasons why a negotiation with Schaub is problematic:
Injury history: Schaub has missed 16 games in five seasons with Houston. He's missed at least five games three times. Perhaps he's just not lucky, but top-shelf quarterbacks are paid in part for their durability.
T.J. Yates: How high is the ceiling of the second-year player? Yates showed as a rookie that he could eventually be a better player than Schaub. If Gary Kubiak truly believes in Yates, he could make a dramatic change in 2013.
The franchise tag: Keeping Schaub on a one-year deal next year would be expensive. But it's not a bad fallback plan for a team trying to win now. Schaub likely has more to prove to the Texans to get the contract he wants.
