For me a) its the unknown factor of the colts secondary. Bunch of new players we dont know about .how quickly we adjust to their physical play could be important. I wish indy had david and harper still. b)our Defensive tackling which has improved but will face a bigger test this week.BB showed the addai cutbacks as a big threat on all access show.Iam sure thats something he is harping on as well.Also how the D can sustain its stamina over the period of the game. Last yr the colts no huddle wore them down. I guess it depends a lot on how our offense executes . Lot of people are predicting a blowout. Iam not so sure. We havent been able to stop manning last 3 times . We have better personnel now but he now seems a bit more comfortable with the scheme the pats play. what do you guys think ?
