The Baltimore Ravens had scored three points in 27 minutes and trailed the unbeaten Houston Texans. Ray Rice was unavailable, the offense was struggling and the usually boisterous crowd was eerily quiet. The defending Super Bowl champs were in dire need of a game-changing play, and Daryl Smith was there to provide it. Smith stepped in front of tight end Owen Daniels, intercepted Matt Schaub's pass and took it 37 yards for a touchdown to propel the Ravens to a 30-9 victory Sunday.
