Everyone is focusing on the offensive aspect of the game and overlooking defense. IMO Titans defense is a lot more stout than the Chiefs. They play a lot more physical. Similar to the Ravens and Steelers. So, I would not be so quick to discount them.
Also, as another poster mentioned, we beat a high powered offensive teams in the Saints and Packers. And lost against a stout defensive running team in the Ravens.
Another thing to consider. Would it be tougher playing a post season chocker Andy Reid or x3 SB champion Mike Vrabel? (Tbh not really too familiar with Vrabel coaching style. I just believe his big game experience would help him not get flustered like Reid in years past)
That being said, I'm 50/50. Both teams scare me for different reasons. But, if you held a gun to my head I would go with the Chiefs. Just because I know the whole world would be jocking them leading up, making it much sweeter if we win.
