That whole offense should just be centered around runs with Charles or Hillis and screen passes to Charles or Hillis. They ask a guy like Matt Cassel to throw bombs downfield to Bowe. They should throw that in there once in a while, but mostly go with screen passes, tosses, and runs, maybe some trick plays and option type plays. Or even the Wildcat! This team was totally ruined by bad coaching.
If you think the Chiefs offense is asking Cassel to throw deep to Bowe all game long, I don't think you're watching the games. It's first down, predictable run play gets stuffed. Second down, 3 yard pass to the flats. Third down, incomplete pass down the middle or interception on an out route. They tried the Wildcat a couple of times against Oakland and it fell pretty flat.
