On paper the Texans have the best team in this division.
If Matt Schaub can stay healthy they will win the division.
Indy, and Tennessee will both be solid, but I see both of them finishing around .500
Jacksonville on the other hand I don't like at all. Bad defense, brutal schedule, and outside of MJD really not that much on the offensive. Expect Jack Del rio to be fired by season's end, even though I really don't think he deserves to be. He's a very good coach, who I think has gotten alot done with limited talen the last few years.
But the only way most people judge coaches is on wins and loses, and a losing coach is not a good coach in most people's eyes, regardless of the situation he's in.
