Arthur Arkush over at PFW hits it on the head, SF should do well, we'll wonder about the rest...
PHIs loss is KCs gain in Andy Reid and this considerable staff. KC will be better, the draft will hint at how much better, then it's on to OTCs, TC and preseason. Barring injuries, KC should be in the upper half of the AFC, their D is underrated by many, their O should be awakened by Andy & Co.
The lower half of the AFC should include BUF, NYJ, CLE, TEN, JAC, SD, OAK and here's a thought... IND. Why IND? w/OC/acting HC Arians moving on to ARI, I think a regression will occur. I could pick on CIN or even MIA, but CIN has more to work with as far as personnel especially on D, they do however play against the AFC North rivals of BAL, PIT and CLE, which is perhaps the toughest AFC division.
MIA also has much better players on D than IND and appear to have continuity on O which is the same as CIN, thus though IND went to the playoffs this past season, I expect a regression to occur for this upcoming season. IND may prove me wrong and do better than KC with their W/L record, but we'll need to wait and see... right?
On the other hand history does have a way of repeating itself and CHFF has an article on KC and their history of QB's see http://www.coldhardfootballfacts.com/content/alex-over-geno-smith-kansas-city-chiefs-history-thrift-store-qbs/21613/
So will the funk hit KC and their next QB? Time will tell...
