Those teams you mentioned - the Colts, Texans, Steelers and Bengals - have a huge advantage over the Chiefs. They aren't in year one of a new system installing a completely new offense, defense, etc.
We're an 8-8 team at best next year. 2014 we can start talking playoffs if Alex Smith isn't a disaster.
I also think the Chargers are a sleeper.
The Chiefs will finish 5-11, Alex Smith will play horribly, and Geno and I will cackle with glee while he burns Kansas City.
