They play much of the same schedule this year so it will be interesting. Barring injuries (like we had last year), adding up Carr's experience, the receiver's chemistry, Davis being the starter from the beginning, a very tough looking O line, the return of G-funk, Payne, and Glenn, exciting changes in the secondary, and apparently not as tough a schedule as we had last year - I'll say Houston 10 wins, and playoff birth.
For the cowboys, despite the leadership of the Tuna, both Coughlin, and Dennis Green will steal one away from them, and Joe Gibbs will beat them both times. Carter isn't the answer at QB, and Henson will make plenty of mistakes in his first year appearances. Tuna doesn't do too well when his team is struggling - so I'd look for them to post at best 8 wins.
