Time for Texans to trade Tate?

The Houston Texans' 2013 campaign is not yet in the grave, but their "vitals" are headed in the wrong direction. They have lost four straight games, which puts them three losses behind the first-place Indianapolis Colts in the AFC South (though the Colts will have to win Monday night to maintain that lead). Starting quarterback Matt Schaub has been a mess, and now is injured. If he misses Week 7, backups T.J. Yates and Case Keenum will have their work cut out for them on the road against the undefeated Kansas City Chiefs. If they fall to 2-5, that may signify the final nail in the coffin as they head into their Week 8 bye.
