I think even Mills could hand it off to Chubb and Hunt pretty well all game.
One thing that might favor the Texans is Watson trying to do too much to stick it to Houston, in Houston.
And if Texans fans weren't in such an apathetic state towards the Texans, having the stands full of fans booing his every move, signage, and waving little towels might have had an effect. Maybe they do have a larger crowd just to show what they think of him, but I think just as many will be there who support him and/or the Browns in general.
