With the parody in the NFL it's very possible to have a great year with better than average talent.
The Texans have some of the best young talent in the league and seem ready to take the next step. If not for the turnovers in the first two games last year they would of won 9-10 games. There just aren't that many elite teams and with some decent confidence I think the Texans should easily make the playoffs. The O-line should be vastly improved with a year under its belt and the D will wreak havoc if they can get decent pressure. If they can stay relatively healthy 10-11 wins doesn't seem like too much of a stretch.
