Cassel has enough pieces around him to win the AFC West.
I'm watching the Chiefs game right now and I am really liking how the Chiefs look on both sides of the ball. Charles and Hillis compliment each other very well and you have some nice weapons at the WR position. Once Bowe is back in the mix having him alongside Baldwin and now McCluster in the slot is a nice trio. I didn't even mention Cyrus Gray who looked good as well.
Romeo has the D playing good as well which I saw late in the year last season so it seems to have carried over. Only preseason but it's a nice sign from KC.
