You guys do realize that in many games against good teams, the Texans have had sizeable leads at half time only to lose. They had a 20-3 lead against the Seahawks and 21-3 lead against the Colts.
I said earlier in the week that the Pats needed to treat this like a playoff game because that's the effort they were going to get from Houston. So far they've been lethargic and the result is an early 10-0 hole.
