The Chiefs season is going to go one of two ways.
1. Everyone on the team keeps getting hurt and they never go into a game having all their ammunition. If this happens the ceiling is losing a first round playoff game. It would actually be better not to make the playoffs at all in this scenario. It would give them better draft positioning and one less game for key players to get injured in. If they aren't in position to win the whole thing then let's have as few off season surgeries as possible.
2. Everyone on the team eventually gets healthy and the team plays its best football of the season in January. If that happens I don't care who they are playing or where they are playing them. The Chiefs will be the team that no other playoff team wants to play. The Chiefs do not play in a dome. They should have no built-in disadvantage to playing on the road. I don't believe any team or stadium anywhere has a magic spell over other teams. Home field advantage is only an advantage if the visiting team does not think they are as good as the home team that is why New England has so much success at home in the playoffs. Teams aren't afraid of playing New England in Foxboro in the playoffs. Teams are afraid of playing New England anywhere in the playoffs and it just so happens that those games are usually in Foxboro. If the Chiefs are healthy that won't be the case. Yes, they could still lose (if Tim Tebow can win a playoff game anything is possible in the playoffs) but they would not be pretender.
Either way it is all up to the weekly injury report and nothing I do is going to influence that so why worry about it.
