They will decide the #1 seed in AFC South.
I was wondering about theses games, it will be all about defense.
Colts has great offensive weapons but if you take look on Texans defense it is kind of scary JJWatt, Clowney, Louis Nix, Mercilus, Clemons. If Pagano decides run the football it is a lost game and Colt's Oline must do a great job and give enough time to Luck throws, with few opportunities Colts can score easily.
Texans doesn't have a franchise QB but still got Hopkins and Johnson, the secondary must be like hawks on theses guys and I am not comfortable with Toler and the others depth players. Texans' running game looks good with Foster and Sua'Filo if you remember last year Colts' run defense was like swiss chess but this year it looks good against the run with Jones, RJF, Redding, Jackson and Freeman.
The key for a winning is hold Texans' pass rush and play like a top 10 defense. The defense which plays the best football will come out whit a W.
