Matt Schaub will make the start in Sunday's Week 16 game against the Broncos. Case Keenum sprained his right (throwing) thumb against the Colts last week and has been ruled out. Schaub can't play any worse that Keenum has been playing, but we wouldn't expect him to be much better. The Broncos will likely blow the Texans out, leaving plenty of garbage-time throws for Schaub. He's not a fantasy option, but we wouldn't downgrade Andre Johnson at all.
