I think you will be alright with either Carolina or Houston. both have their upsides ...
Cam is a rookie, and this will be his first pro football game at full speed, I dont think he will be able to handle it, I forsee at least a couple of INT's and not many long completions. the only downside, is that he will be rushed and Cam can handle himself on his feet! He might end up having half as much rushing yards as passing! lol
Houston has re-vamped their defense ... and with the addition of JJ Watt on the line and Mario as an OLB and a great new defensive coordinator, I see them being an decent defensive team. I still think that the Texans weak point is their secondary, but thats what makes this week a good matchup for them against the non-Manning Colts, I see the colts running more than passing, and houston will stop them.
If it was up to me, I would go with the Texans ... but then again, they are my team!
Best of luck!
