Lots of things to respond to.
As for teams getting the jump on us, you know the fact that, in most cases, the Bills adjust. Does that not matter more?
If you think Allen gets us 12-13 wins, then you're saying coaches don't matter.
Lastly, you make a big leap saying things end the same way. They might be losses but they aren't for the same reasons. Thinking changing one head coach is the answer is the height of arrogance. Maybe you missed the part that no other NFL team has solved the Chiefs riddle the past three years. You think you're going to find the one guy smarter than Ried?
