Because we've more or less dominated the game. If we'd been able to put it in the endzone when we were supposed to, we'd be up by 21.
B/c the Texans HAVE dominated this game offensively, they are winning the TOP and turnover battle, and their FG's have all come from short distance (meaning the Texans had a great chance to get a TD on each of those drives).
when i play basketball, the one guy i hate playing against is the short quick guy. Thats what Sproles is.
